So I know this may seem very very noobish.. I am attempting to clean up a failed attempt on dual boot winxp on win 7. In the process I pushed a few to many button and deleted my MBR partition. Now the volume is unallocated and attached is picture of my disk management. Question is: 1. If i turn computer off/reset/hibernate will I have issues trying to boot into my OS 2. If the unallocated 10 gb. isn't needed for the MBR (i dont know why it's 10 gb..) what can it be used for.. Any more info just ask I'll be more then happy to reply.. p.s my computer when bought didn't come with win 7 recovery CD's. so in the mean time - no resets *edit* If I managed to place this in the wrong section please move, I had a hard time deciding if this is a software, hardware, or an I'm and idiot issue and my question landed here.
