Reformatting entire dual-boot system worries
OK, I think I want to back everything up on my XP/Mandrake 9 system. The partitioning went fine and all installations were OK, but I have a load of junk and just want to start over.
Here's the worry. Presumably I can format my ntfs partition as part of the XP installer (all *nix purists who want to start shouting at this point may as well go jump off a cliff), but I have no clue how best to remove/reinstall Mandrake. I'm concerned that by simply removing its partition I may screw up the MBR, or somehow end up with a bootloader that's looking in the wrong places for bootable OSes.
If anyone has done a similar thing please let me know, or any theoretical risk-assessments or reassurance would be greatly appreciated. I'm a 98% newbie, hence the technie uncertainty and eagerness to wash away my Linux beginnings, so go easy...
Thanks as ever,
