I have 3 operating systems on my Computer. Drive C is Active and Primary and has Win Xp. Drive D has Wind 7 Drive E is used for my data and backups. after that i installed Red Hat Enterprise Linux 5. i have the concepts about the boot loader. i dont want to keep XP now. and want to format the drive C to get rid of XP. but i m afraid that if i format the C Drive my Win 7 will not boot. what should i do? My C Drive having Xp is of 30 GB. i want that 30 GB space. what should i do so that i get the space and there would be no boot problem for win 7.
