I have the exact the same error
2215-EIT failure. VA boot record read failure.
Ensure drive with VA image is installed correctly.
It's a HP Compaq dc7800 Small Form Factor PC
System BIOS 786F1, V01.04
Maybe it has something to do with MEBx.
I have tried to make CMOS reset, reboot & press CTRL + P at boot but I can't access to MEBx.
the result: " Error message disappear, but I can't access & have a message like
" Attempting boot from CD-ROM
Attempting boot from Hypervisor "
Thank you for help.
