if i use fixmbr with it delete all my work that i have on my HDD? or will it fix the problem of NTLDR missing? thanks

It shouldn't - but if possible (in fact it would be very wise to) run a virus scan first? Otherwise there 'is' a chance the partition 'may' become inaccessible... viz: FIXMBR fixmbr device name Use this command to repair the master boot record (MBR) of the boot partition. In the command syntax, device name is an optional device name that specifies the device that needs a new MBR. Use this command if a virus has damaged the MBR and Windows cannot start. WARNING: This command can damage your partition tables if a virus is present or a hardware problem exists. Using this command can result in inaccessible partitions. Microsoft recommends that you run antivirus software before you use this command. You can obtain the device name from the output of the map command. If you do not specify a device name, the MBR of the boot device is repaired, for example: fixmbr \device\harddisk2 If FIXMBR detects an invalid or non-standard partition table signature, FIXMBR prompts you for permission before rewriting the MBR. FIXMBR is supported only on x86-based computers. extracted from MS KB at: http://support.microsoft.com/?kbid=314058 Also have a read of: http://www.michaelstevenstech.com/XPrepairinstall.htm http://www.wown.info/j_helmig/wxprcons.htm If you can back-up data etc first - it doesn't hurt to (just to be safe...); but a fixboot and/or fixmbr should be safe - as long as you have managed to clear any resident virus problems. (Also, some folks suggest temporarily disable anti-virus util in bios when running setup\repair routines - they likewise may get in the way of a repair?).
