Have Macbook Pro, with 10.6 - all fine until.... I used Bootcamp to set up 10GB partition, then inserted my Windows XP (Home) Disk. When the I was shown the partition table, the only partition was C: 131GB. So I quitted, and since then on booting I get a black screen with flashing cursor in top left corner. The hard drive is inaccessible - for example it does not appear as a firewire drive, and in the repair disk options offered from my Windows XP setup disk, when I type the dir command for C: I get an error occurred during directory enumeration. Seems like the boot (Master Boot Record as Windows calls it) is corrupted. From reading threads on different forums I cannot see (or maybe I just cannot understand!) a fix posted anywhere. For example: http://forums.macrumors.com/showthread.php?t=630107&highlight= which was on this forum some months ago. also: http://forums.macrumors.com/showthread.php?t=639213&highlight= and http://www.insanelymac.com/forum/lofiversion/index.php/t98888.html If the boot is corrupted, is there any way to re-instate it without having to reformat the whole drive?
