calimero_zh Posted April 14, 2008 Share Posted April 14, 2008 Hello everybody due to a regrettable BootCamp error, my partitions on my 186.3 GB HD have been messed up. As I did not reformat or install anything new in the meantime, I'd like just to restore my GUID partition table to the state it has been when I bought the laptop (March 2008). Disk Utility is of no use, just shows me Partition Map Scheme unformatted, which means I can use nothing there (Repair Disk etc). On a terminal, fdisk shows the MBR on disk0: one partition of type 04 (DOS FAT-16) starting at sector 1 with a size of 268435455 bits, which means 32 GB. My question is: can I restore my sytem to what it was before (that is without losing data) by just manipulating the MBR table to show -a partition 1 of type ab (Bootable Mac OS X) - a partition 2 of type af (Normal HFS+ partition) Does anyone have the exact numbers for the first and second partition? Maybe a screenshot of the fdisk print for a sane Mac OS installation? I'd be very grateful for an answer!

I made the mistake of using boot camp to see what trying to install windows xp on my iMac would be like and have been regretting it for days. I Feel the same as you do though about trying to just change the partition headers as I am sure my data didn't get erased. Did you ever find a solution to this problem? or a print of fdisk from another mac? muchas gracias, neal Link to comment https://www.insanelymac.com/forum/topic/99184-factory-configuration-for-macbook-pro/#findComment-1138425 Share on other sites More sharing options...
