I was trying to fresh install Win 8.1. It has Win8 previously and was working fine.
After I plugged in the Win 8.1 boot usb, it stuck at thinkpad boot screen and cont. rebooting.
Only thing changed in BIOS is moving USB boot up higher and disabled Computrace. Earlier it was enabled.
I can still get to BIOS by F1.
Looked all the USB port. None of USB ports are damaged or pins shorting each other. I also tested the HD by putting in my other working T500. HD is fine. Restored BIOS to default as well but no luck.
Tried all the method including CMOS reset, but no help.
Thanks for the help!

No, it does stuck in the same loop. Continuously booting and showing Thinkpad boot screen again and again.
I took the HDD out and no USB connected. same behaviour with or without HDD.
In BIOS startup is set to both - Legacy and UFEI.
Only change I had made prior to installing Win 8.1 is turn off Intel Anti theft module under security in BIOS.
