I posted something else in the "Am i infected forum" that might belong here, my problem has transgressed from viral to microsoft issues :flowers:

I am running Microsoft Windows XP Professional on a Lenovo Thinkpad z60m.

I am pretty sure I got Antivirus pro so I tried to restart in safe mode and got stuck in a loop

The usual blue screen appears after trying to bootin safe mode with
""A PROBLEM HAS BEEN DETECTED AND WINDOWS HAS BEEN SUT DOWN TO PREVENT DAMAGE TO YOUR COMPUTER.

IF THIS IS THE FIRST TIME YOU'VE SEEN THIS ERROR SCREEN RESTART YOUR
COMPUTER. IF THIS SCREEN APPEARS AGAIN FOLLOW THESE STEPS:

CHECK FOR VIRUSES ON YOUR COMPUTER. REMOVE ANY NEWLY INSTALLED HARD DRIVES OR HARD DRIVE CONTROLLERS. CHECK YOUR HARD DRIVE TO MAKES SURE IT IS PROPERLY CONFIGURED AND TERMINATED. RUN CHKDISK /F TO CHECK FOR HARDDRIVE CORRUPTION, AND THEN RESTART YOUR COMPUTER.

TECHNICAL INFORMATION:
--(some error codes)--"

unfortunately i cannot reboot in any other mode such as safe mode, normal mode, best configuration, debugging mode etc.

Similar problems have been reported with the computer being stuck in safe mode loop after a virus.

Solutions posted have been succesfull and are as follows:

open windows recovery console
get to c:\windows

enter: bootcfg /rebuild

rebuild the boot.ini file

issue occurs here: when i bootcfg /rebuild the os location: comes up as blank

notethat bootcfg /list yields 4 results
1,2,3 are ones i have created...the third one is:
[3] "microsoft Windows XP Professional"
OS Load Options: /fastdetect
OS Location:

the original boot is as follows:
[4] "Microsoft Windows XP Professional"
OS Load options: /fastdetect /safeboot:minimal
OS Location: C:\windows

So obviously i am stuck with [4] because 1,2,3 will not load the windows os...
issue with 4 is that the /safeboot:minimal keeps me in safe mode---which is corrupt

So
a) how do i fix the issue with locating the correct os bootcfg/ scan yields the blank one
or
:thumbsup: how to i edit [4] to erase the /safeboot:minimal

any help is appreciated.

note i also tried

fixmbr c:
fixboot c:

no effect or positive result

I don't understand. If you were stuck in that loop, as I am, how did you copy the boot.ini file to the corrupted machine? I'm using a sony vaio and i can only get to the BIOS, which isn't allowing me to change anything.

Or you may be able to use the Recovery Console:
