Long story short, I got a Lenovo Y500 laptop and wanna try how the old XP x64 SP2 will run on it compared to Win 7 x64. (I finally saw the Windows 8 crapware with my own eyes and wiped it out at the second day after purchase) Windows 7 x64 installs with no problem, but the installation of XP x64 is stuck at the point after initial files copying (Message "Installing Windows..." BEFORE the fist reboot). No BSOD, no code beeping, just a black screen like a display adapter is down, CPU fan throttling to 100% speed and then full hard shutdown. I tried the "forged copying" as alternative installation method. Took off the HDD, placed it in the other PC, interrupted installation at the first restart checkpoint and put it back to Y500 to continue. No way, it went hard shutdown as soon as the splashscreen appeared. For testing, I tried even to install XP x86 - the same story. Finally, I replaced the Y500 HDD with the one from old dead PC that once had the XP x64 installed and tried to boot in Safe Mode. There I noticed that Windows is hanging with the same behavior at the acpitabl.bat file. I got all the drivers (except of USB 3.0 that isn't supported in XP) and was about to perform the XP-7 comparison, but stuck at this damn error and it drives me really MAD Any help for shooting this trouble will be greatly appreciated.
