I tried booting up Linux off of a pre-set up thumb drive and now my PC is getting the INACCESSIBLE_BOOT_DEVICE error

Whenever I boot up my PC I get a blue screen with the already mentioned error code on the screen. My PC then automatically restarts and brings me into recovery mode. I only have 6 options and the only option that actually does anything at all is the command prompt.

In case it's important, the other options in troubleshooting are: startup repair, UEFI firmware settings, system restore, uninstall updates, and system image recovery. When pressing startup repair it just tells me that it couldn't repair my PC. Selecting system restore, it tells me that I must specify which Windows installation to restore, the rest just dont do anything.

Messing around in the cmd prompt, I typed in chkdsk, and it says that the volume is in use by another process near the beginning of the assessment. Another command is tried was "bootrec/rebuildbcd" and it says that total identified windows installations is 0.

From here I've been lost on what exactly I should do after researching this problem online, the only things im able to do on my PC are using the cmd prompt and open the BIOS systems, which is from Omen, and is basically nothing like ive ever seen online in other BIOS systems.

Can someone help me boot up my PC normally again? Hoping to get this problem fixed before I choose to take it to get repaired by a professional, if anyone could spare some help, please, thank you, and have a nice day.

    All i did was go into Boot options in BIOS setup, enabled USB boot, then went back to BIOS Startup menu, selected boot menu, and then selected the thumbdrive that supposedly had Linux on it. That was when the problems started, and Linux never did boot up. Ive since taken the thumbdrive out in fear that it might damage my systems more

    Hi ,

    I understand CSM and to have Legacy BIOS support.

    What configuration did you make in the BIOS to boot from USB Flash initially?

    Did you manage to boot into Linux?

    Hi ,

    I am Ivan, I will help you with this.

    Well when you tried to boot from the USB Flash driver to start Linux did you disable Secure Boot and enable CSM or something similar?
