Computer was having startup problems. Would log into a black screen with a blue bar. Restarted and pressed F4 to start recover (decided to go to factory settings). Froze while configuring environment and shut off. When restarted, it would instantly go to the F12 boot menu. Created a recovery drive with my Toshiba USB HDD. However, the bios does not detect it as a bootable device. What is going on, and what are my options?

What type of Toshiba USB HDD is it? and was the drive connected to your system when you had the boot issues? also, depending on your bios, and the size of the external drive, it might not be able to see it and if you don't have an active partition on the USB drive, it won't be able to boot from it. (Just to clarify, it may have a partition on it, as it would have to otherwise it would just be raw space, but that partition will most likely not be set as active for booting, and the only way to do this manually is through diskpart from an elevated command prompt)

The HDD is a Toshiba Automatic Backup Portable Drive with 1 TB of memory. Model number 593701-B. And yes when I ran the restore it was connected to the computer. And before the crash it was recognized by the computer. How exactly would I use an elevated command promt (not exactly experience with programming).

Hi there,

To get to an elevated command prompt, you can right click on the command prompt icon and select run as administrator, this will of course require you to have administrator access on the system you do this on, and then with the drive attached to the system, run "diskpart" at the command and use the following commands:

list disk
select disk "number" (the number will be replaced by the disk number in the list that is returned by the first command)
clean
create partition primary
select partition 1
active
format fs=ntfs quick
exit

That list of commands will clear everything off the disc, so if you have data on there, I would suggest either skipping the clean and create partition primary commands, and use list partition to see what partition to choose from the list, the same way you do with the disk...

Now I will advise caution, as Diskpart is a very dangerous tool if used incorrectly.

Another option that you might wanna look at is using Disk Management under Windows, to get to this, right click on Computer and click Manage (will need admin access) and then go to Disk Management and check the status of the drive that way

I'm guessing the BIOS does not recognize your external hard drive due to the HDD mode or USB mode.

Try disabling USB3 in the bios (setting it to USB2). That will be slower, but more compatible.

The 2nd thing to try is checking the SATA controller in the BIOS and trying the other settings. Generally they are set to ACHI, SATA or RAID. Try the different modes to see if your hard drive is recognized. Normally this would be set to SATA if you only have hard drives, or ACHI if you have hard drives and optical drives.
