Windows XP/7 won't boot after converting to virtual machine - 0x7B BSOD
May 24, 2022

You may need to make sure the hard drive controller is set to IDE instead of SATA.

The Hard Drive Controllers registry keys need to be rebuilt.
https://www.hirensbootcd.org/files/Hirens.BootCD.15.2.zip
Boot it in "Mini Windows XP".
Click icon in system tray, then choose Registry -> "Fix hard disk controller (fix_hdc.cmd)".
