Hard drive not showing up in BIOS boot options

From everything I've read it appeared that my computer should recognize the new hard drive automatically, but it is not doing that and is not booting up. When I go into the boot options in the Phoenix BIOS, it only lists: F10 and F12 Delay (sec), CD-ROM Boot [Enabled], Floppy Boot [Enabled], and Internal Network Adapter Boot [Disabled] If when you turn on your Windows 10 computer and it fails to boot successfully and you access the BIOS/UEFI and notice that the disk drive (HDD/SSD) is not showing or listed on the boot menu, then.

Enable Hard Drive in BIOS Applies to: Fix HDD not detected in BIOS error directly by enabling hard disk in BIOS. Step 1. Shut down the PC and restart the PC and press F2/F8/F11 or Delete to enter BIOS In the BIOS setup menu, select the Boot tab and press Enter. Check the boot order and make sure your PC's hard drive is in the first slot. If not, swap the order of boot devices so that your hard drive is first. Highlight Boot Mode, press Enter, and swap from UEFI to Legacy Support Out of the 4 drives, only 2 showed in Boot Priority which are my OS SSD and my optical drive. My 2 other hard disk drives were not showed up in the boot priority, but it does showed up in boot menu, SATA Information on the EZ Mode tab, Boot Override tab in the Advanced Mode, and Hard Drive BBS Priorities I suspected somehow the boot order got mixed up, so I went into the BIOS only to find that both my SSD and HDD do not show up in the boot order dialogue. I found this weird, but even weirder is that if I hold f11 on boot and boot from all of my drives appear, and I can boot normally from my SSD

When you boot your PC with the BIOS set to UEFI mode, then be sure to select the W8 boot media in the boot menu designated by EFI. Once you do that then W8 will create the required partitions and the hard drive will be formatted as GPT. HP ENVY 6055, HP Deskjet 1112 HP Envy 17, i7-8550u,16GB, 512GB NVMe, 4K screen, Windows 10 x6 That would then not report to a system post the hard drive as available. Is the laptop still able to get to the BIOS ? if I have understood you right I would personally use a bootable USB drive and set the BIOS to allow to boot from USB. if that will boot for you then it could well be a simple case of a replacement hard drive Booted Ubuntu-16.04.3-desktop-amd64 image from usb drive in UEFI mode. Installed without errors. And I'm having the same problem of the system not recognizing the install. Just boots into bios every time. So far I have checked the following: In BIOS eMMC is present. In BIOS no operating system shows on Hard Disk at Boot options - just Hard Disk

BIOS missing internal hard drive boot option - Microsoft

  1. Alright. I go into BIOS but under BOOT, the SSD doesn't show up. I can only see my bootable Windows USB which is set to Boot Priority #1. If the SSD is disabled, I can't enable the drive because the bios is SO bare bones that I can't Change SATA Controller Mode as there is no option like that in the BIOS
  2. If the hard drive does not show up in BIOS, gather as much information about your PC as you can and write it down. Such as the model and manufacturer of the drive, the manufacturer of the computer or motherboard, and the BIOS manufacturer as well as the version. The latter can often be found splashed across the screen when you first boot the PC
  3. @Anonymous the USB Boot Device in the full BIOS Setup (F2) is just a generic entry. That doesn't appear or disappear based on whether you have a USB boot device connected at the time you access that menu. The F12 menu is dynamically populated based on what boot options are actually available at that time
  4. Re: UEFI boot sequence empty, hard drive not showing The problem is that the UEFI boot loader needs to be rebuilt, either manually (see the first link I posted) or by reloading Windows (the second link). Until that's rebuilt, the system won't find a bootable drive
  5. The hard drive you are trying to boot from should show up in the BIOS Advanced mode under Boot/Hard Drive BBS Properties. Click on Boot Option 1 and see if it is listed. If it is, select it. If it is not listed, your only option is to flash Bios version 2104
  6. I would like to install a Boot Manager on the secondary drive and need it to appear as an option in the BIOS Boot sequence. It is not showing up. The secondary drive is visible in Windows Explorer as drive D, and it can be seen as active and online by Computer Manager
  7. Re: Hdd show in hard drive menu in bios but not in boot priority. Let me explain step by step. 1 - I bought new pc. 5 - I checked BIOS. 8 - I figured that there is no HDD in boot menu when pressing F12. 9 - Boot priority menu has ONLY, LAN boot and DVD boot option

Anyways, I managed to install, and boot from the NVME drive with that setting set to Legacy/UEFI, even though it still doesn't show up in the Boot options as a drive, only as a Windows Boot something, I cant remember the exact name, but it boots. I tried doing the same thing with it set to UEFI only, but then it keeps booting into the USB drive Later when the cloning was complete my system was shut down, then I went to my BIOS to change the sequence in the boot options but strangely the Samsung 970 Evo Plus didn't show up on the list of available boot drives to change the boot priority. I could only see the windows boot manager for my preinstalled hard disk on the boot options If your hard disk is not being detected in BIOS, it is possible that the drive has not been set up yet. To set up the drive, follow the steps below. 'Restart' your computer and press the 'F2' key or any key according to your PC Note: Different PC manufacturers use different keys to enter the system BIOS Place Windows disk in your system and boot from it. Now, tap on Repair your computer after selecting the language, time, and keyboard input. choose the Windows installation drive, which is C:\ most of the time, and click Next. Choose command prompt when you see system recovery options on the screen

Hard Disk Not Detected (Windows & BIOS): How to Fix Hard

Veteran. 3. First, Check what format the M.2 drive is in. UEFI bios won't see an NTFS drive as a bootable device. The bios will see it, but it's not something you can boot from. Unless I'm mistaken, it needs to be in FAT32 to be bootable via UEFI. But most OS installs are smart enough to only install on properly formatted drives When I open the BIOS and check under boot devices my SSD doesn't show up, however if I go to boot override I can boot off my SSD. I have ignored it for a while because I am still able to boot and everything is fine, but it is kind of annoying having to go into the BIOS and do a boot override every time I boot Personally, I am not familiar with your specific computer but it's hard for me to accept there is no USB drive option to boot from. However, due to Win 10, Secure Boot technology and UEFI, there is some tricks. . Additionally, in the BIOS it be called USB hard drive and not USB pen drive So I got my adapter for SATA to USB and plugged in an external hard drive which allowed me to update the bios this is where it gets kinda funny. I think at some point I must have changed the boot setting from UEFI to Legacy which for some reason makes the drive not show up in the BIOS. This was... - Lenovo Yoga-900-13ISK The other drives do not appear at all, which includes the SSD the Win 10 is installed on. So what I need to do is press F12 (boot options), and then it becomes visible and I can boot to my SSD. I would have to do this ever-single-reboot as its not set in bios as the #1 boot option

[SOLVED] Boot Device Missing How to Fix an Inaccessible

  1. My problem is that I have a standard (CSM, Legacy) Windows 10 installation so EasyUEFI doesn't not works, it displays a message that only works in UEFI. I have been experimented with MacOS X and I have one or two UEFI boot entries I want to delete. My motherboard is Asus P8H61 s1155 and I haven't seen in BIOS any option to delete these entries
  2. Start your computer from the installation media, Insert the DVD or USB flash drive and restart your computer. If you see a message asking you to Press any key to boot from DVD, do so. If you don't see the message, you might need to change the boot order in your computer's BIOS settings so that it first starts from the DVD or USB
  3. In Step 4, we set the first boot device to the CD-ROM Drive as an example. As you can see in the screenshot above, the computer is attempting to boot from the CD but is asking for a confirmation first. This only happens on some bootable CDs and will not show up when booting to Windows or other operating systems on a hard drive
  4. Maybe we need to disable the setting like Fast Boot or Secure boot or other similar name in BIOS, the BIOS settings are different depending on the model of the machine, we can search it online if we can find the setting. Then we may see legacy boot (it is also called MBR boot) and UEFI boot. We go to see if HDD will show up in BIOS Boot.
  5. Solution 1: Enable drive in BIOS. If your hard disk is not being detected in BIOS, it is possible that the drive has not been set up yet. To set up the drive, follow the steps below. 'Restart' your computer and press the 'F2' key or any key according to your PC. Note: Different PC manufacturers use different keys to enter the system BIOS

Solved: HDD not found/detected when Boot in UEFI mode - HP

Hi there, I am wondering if someone can help me work out why my internal hard drives aren't showing up in the BIOS. When I enable the RAID controller and set up an array they are detected and placed online, but if I remove the RAID array they do not show up in the BIOS as a device from which I can boot from I am able to boot from the USB drive connected to the console dongle and it finds the virtual disk and loads the OS. When I try to install again, it informs me that it recognizes that the installation already exists. It's just a matter of getting it to boot from that disk. It looks like the BIOS can see the RAID card, but no option to boot from it I finally got the system to recognize the USB drive by burning it with Balena Etcher (other methods of burning the .iso file to the USB drive made a drive that the boot menu didn't recognize). That allowed me to boot into a live Ubuntu, but the hard drive I wanted to install on didn't show up

Computer can't get past BIOS, and doesn't have any boot

  1. 8. Previously, before formatting the hard drive, I upgraded to the latest BIOS version 208 but that did no reveal any boot options. 9. Yes, I have disabled secure boot. There are no options for selecting legacy boot. 10. So now, I cannot boot to any device, even the SSD hard drive is not listed under boot options, all I get is the BIOS
  2. BUT If I go to the Bios Boot page, the SSD is nowhere in the boot priority list, so I cannot make it the default boot drive.

  3. Looks like the drive letters are also abit messed up. First step then as a test. Go into BIOS and then the BOOT tab, then disable the CSM. Reboot machine and see if you can see either of the hard drives. If not then we now know the HD's are in MBR format, not GPT. If that is the case, then the same applies. Active partition and C drive need to.
  4. My problems was that i installed windows after creating a new volume of my m.2 & it caused my bios to not detect it as a possible boot drive. So i formated my m.2, deleted the volume & reinstalled windows. After that it was working again. I don't know if it's the same problem, but i hope it helps
