BSOD Win 2008r2 what could be the problem?

Question

System administration

Iron car rented from hetzner. 2 SSD 480 disks. Hyper-threading is disabled in the BIOS, AHCI disk mode .

Windows 2008 r2 enterprise installed via Rescue System according to this https://blog.rodney.io/2016/06/installing-windows-... manual via temporary (portable) qemu-kvm. The qemu-kvm is up and running. But if you take it out of Rescue mode, then for a second you can see the windows boot bar further BSOD 0x0000007B It was deducted that this is INACCESSIBLE_BOOT_DEVICE

Tried to switch to RAID and reinstall - it does not help. How to deliver drivers or what could it be?

Answer 1

I don’t see in the instructions that there was an AHCI emulation key in QEMU.
Change BIOS to Legacy\IDE mode.
And drivers for SATA controllers - yes, they must be integrated into the distribution kit - if they are not in it or the standard ones do not fit.

Answer 2

The problem could not be solved, it partially became clear that one of the images lacked drivers. Found another image from 2008 r2.
People from Hetzner contacted because of the strangeness that the remote-kvm rack is often occupied, they offered to install it themselves, we sent them the image.
