What causes the inability to enter Windows XP?

Q: The system is Windows XP with SP2. When prompted, it will prompt “Windows could not start because the following file is missing: \\system32\\driverstfs.sys”, and can't enter the system. How can I solve it?

A: You can enter the recovery console and run the following commands in sequence: (assuming Windows XP is installed on the C drive)

cd system32

ren ntkrnlpa.exe ntkrnlpa.old

ren ntoskrnl.exe ntoskrnl.old

cd "c:\\windows\\driver cache\\i386"

expand sp2.cab -F:ntkrpamp.exe c:\\windows\\system32< Br>

expand sp2.cab -F:ntkrnlmp.exe c:\\windows\\system32

cd c:\\windows\\system32

ren ntkrpamp.exe ntkrnlpa.exe

ren ntkrnlmp.exe ntoskrnl.exe

exit

Tip: If sp2.cab was previously removed, you can run it first “xcopy F:\\i386\\SP2.cab c :\\windows\\driver cache\\i386\\” (This assumes that the F drive is an optical drive).
