I think the issue with canonkong's ACPI.sys fix is correctly explained here, today I tried kebabstorm's ACPI.sys and it seems to work well too.

It looks like they are: Also I got Ethernet working by using this trick, I found version 22.5 of the driver here, the correct driver is located in the PRO2500 folder of the archive, I had to disable driver signing check to get it working properly since it requires INF file modification.

I can confirm, no more 0x0000007B ! The previous ACPI fix I was using wasn't apparently enough for my system.

I just checked and it is 64bit version. :/

@George King's ACPI.sys fix is working ! No more 0x0000007B and I successfully installed his ISO, Windows XP is now booting properly and I did not BIOS downgrade, still on 7D25v13. maybe the fixed ACPI.sys I'm using for Windows 7 has issues ? I used this one.

Oh nice catch, I'll try again with George's XP ISO and see how it goes. Thank you, I didn't tried with the first BIOS (7D25v10), first I tried the latest (7D25v13) then I downgraded to 7D25v11, have you tried those or did you never upgraded ? Also thanks for the link, if I'm still stuck with the 0x0000007B error after replacing the correct ACPI.sys I'll try to downgrade BIOS then use this edition. I hope this will also fix my Windows 7 issue.

Hello, I'm the author of this MDL thread, I'm tired of trying so many things without knowing exactly what's happening behind the scene while getting this 0x0000007B error. I want to be able to get Windows 7 Pro SP1 x64 running but after posting this MDL thread, @George King sent me a PM and asked me to try his Windows XP image, which I did. First I faced the 0x000000A5 error after setup reboot, then I applied this fix, the 0x000000A5 went away but then the 0x0000007B error appeared, this is exactly the same scenario that I got during my Windows 7 setup attempts. After reading some posts of this thread I saw that debugging Windows XP during boot may be possible and I think it is the best way to precisely identify the issue, I'm currently running Windows 11 on my laptop and I can connect it to my desktop using an Ethernet cable. Am I able to debug this error without having a working installed Windows XP? I've never been able to go past the setup reboot because of this 0x0000007B error. Thanks!
