|The syntax of the CHKDSK command it like so...|
CHKDSK /optional switch (d:) ,
(d:) is the drive letter followed by the colon character - if it's omitted, it checks the drive Windows was booted from, which is usually, but not always, C.
If you want to check a different drive letter, type a space, and a drive letter followed by a colon character.
CHKDSK /F D:
CHKDSK /R D:
/optional switch is usually
/F - fix errors found where there is already data
/R - do more tests than /F, check the entire partition including where there is no data, fix any problems found. Takes longer.
CHKDSK typed by itself checks the drive but does not fix errors found.
Usually you use CHDSK /F or CHKDSK /R ,a space between CHKDSK and the /F or /R
"am trying to find out what the problem is with my C drive as it cycles round the start up. it reaches the screen with options of ways to reboot - safe mode etc but no matter what i select the same screen eventually reappears."
Which drive letter the Windows installation sees itself as installed on depends on whether Setup detected other hard drive partitions that have already been assigned drive letters while Setup is running - if it detects any of those, the installation or second installtion of XP (or 2000) will NOT see itself as installed on C
If you are saying that about the original installation, boot that installation and press F8 repeatedly and try choosing
Disable automatic restart on system failure
to see if you then get an error message on a blue screen rather than the computer restarting over and over again.
If that doesn't get you that, try booting the computer from an XP CD with only the first XP installation present and try running CHKDSK /R C: in the Recovery Console.
