Hello,

I upgraded my PC from Windows 7 Home Premium to Windows 7 Pro, using Windows anytime upgrade.
It installed everything successfully, but when it restarted, I got the sweet sweet BSOD, which says:

"Windows did not find any installed, licensed language packs for the system default UI language.
*** STOP: 0x0000012A (0x0000000000000001, 0x0000000000000046, 0x0000000000000000, 0x0000000000000000"

I used the startup repair tool, repaired the boot, still same problem. No I don't have system restore points, and I don't want to format.
I didn't change the English language pack, and didn't do anything. Just upgraded.
I'm unable to access safemode, and I chkdsk'd the drive.

What to do now.
