Boot into Win 7 Log in as administrator
Open Control Panel > Administrative Tools > Computer Management
Select "Disk Management" > rt Click C:
Select "Mark Partition as Active"
Restart and try to format again:)
Just for info dual boot can often be very helpful :)

Probably got bad sectors on your disc, or you need to poulate your disc is disk administrator ------ Control Panel > Administrative Tools > Computer Management > Disk Management > Then set partition on C drive.

Something isn't quite right here.

Win7, same as Vista booted by bootmgr, always calls its residiing partition as the "C" drive whereas those booted by NTLDR are rigidly adhering to the drive designation during the time they were installed. I have a Xp installed in a D drive. I managed to removed the C drive and got it booted up in a D drive when it is the only partition in the hard disk. As for my Vista-64 bit, WIn7-32 and Win7-64 each always boot to its own partition as the "C" drive.

Thus if Xp is booted say in D then there must be a C drive housing its boot loader NTLDR. It could actually be the C drive when Xp is run and then reassigned as D when Win7 is running.

Win7 can be installed in any primary or logical partition later but it always places its boot loader in the first partition recognised by M$ which is the "C" drive. However after booting up it will reassign the drives.

I would be very careful to nuke the Xp partition as it might be where Win7 boot loader bootmgr and the BCD entries are stored.

If a user has xp installed first and put Win7 in later. The newer Win7 boot loader "bootmgr" cannot boot Xp directly. It can only boot NTLDR and let NTLDR boot up its master Xp. All the boot loaders are arranged in the first partition recognised by the M$ systems. Each M$ system must be housed separately in their own partition.
