Hello Celenedh,

I would request you help me with few details to help you in fixing this issue.
-- What is the system Model?
-- Do you get any error code?
-- Please capture the error code if you get any.

I would suggest run a hardware diagnostics to isolate the issue.
-- Restart the computer.
-- Keep tapping the F12 key on the Dell Logo Screen.
-- From the One time boot menu select Diagnostics and Press Enter.
-- It runs a test on all the hardware components.
-- If it test fails please capture the error code and let me know the error code, I would tell you the next course of action.

In case the test passes, follow the next steps.
Check in Safe Mode with Networking.
-- Restart the computer.
-- Keep tapping F8 on the Dell Logo Screen.
-- Once the computer enters Advanced Boot Option, select Safe Mode with Networking.
-- Press Enter.
-- Check if the computer is doing the same thing in safe mode with networking.
Please write back to us with the results.

I also selected Safe Mode with Networking and it gave me the same error code.

It Blue screens with

Stop  0x0000007B (inaccessible boot device)

This is to be expected when the old and the new hardware is not EXACTLY the same.

A Microsoft Windows-based machine may not start up if its system hard disk is transferred to another computer that is a different model.

For example, a user may transfer a system hard disk to a backup computer or may replace the computer's motherboard with a different model.

The following error message will be displayed on a blue screen:

I have a Dell 530s slimline. error code: 0x0000007B, (0xf78a2524, 0xc0000034, 0x00000000, 0x00000000. I ran the hardware diagnostics and came up with the same error codes. tks

Hello,

As Seedstep has correctly said that the issue is caused due to the SATA operation of the Drive is AHCI instead of ATA and Drivers are not installed.
