So i didn't know where else to turn to, I read tons of forums and watched videos and stuff, and now I'm stuck. I set up the partition and installed windows 7. i gave 32gb to windows and am running it off a usb drive that is 320gb. it install successfully and restarted my computer. but then it restarted into a black screen where it said could not find disk partition or something. found the solution online, turned it off, turned it back on holding option. and now I'm back to IOS. but whenever i try to start my computer back up in windows, it can't find the usb drive to load from in the home screen. I read on another forum i believe from here that said to download "rEFit" cus something about it not being formatted right or something?... and i ran the analyze thing and it gave me this: *** Report for internal hard disk *** Current GPT partition table: # Start LBA End LBA Type 1 40 409639 EFI System (FAT) 2 409640 1401379591 Unknown 3 1401379592 1402649127 Mac OS X Boot 4 1402650624 1465147391 Basic Data Current MBR partition table: # A Start LBA End LBA Type 1 1 409639 ee EFI Protective 2 409640 1401379591 ac Apple RAID 3 1401379592 1402649127 ab Mac OS X Boot 4 1402650624 1465147391 0b FAT32 (CHS) MBR contents: Boot Code: None Partition at LBA 40: Boot Code: None (Non-system disk message) File System: FAT32 Listed in GPT as partition 1, type EFI System (FAT) Partition at LBA 409640: Boot Code: None File System: Unknown Listed in GPT as partition 2, type Unknown Listed in MBR as partition 2, type ac Apple RAID Partition at LBA 1401379592: Boot Code: None File System: HFS Extended (HFS+) Listed in GPT as partition 3, type Mac OS X Boot Listed in MBR as partition 3, type ab Mac OS X Boot Partition at LBA 1402650624: Boot Code: None (Non-system disk message) File System: FAT32 Listed in GPT as partition 4, type Basic Data Listed in MBR as partition 4, type 0b FAT32 (CHS) Not sure what it means and what or where i should go from this, but any help would be appreciated. :/ why is it not showing up on the home screen load up even when i hold "option"?
