Lost Mac partition after aborted WinXP installation Bootcamp

by bulldozer84 / January 6, 2010 10:42 PM PST

Yesterday i decided to install Win XP in a bootcamp partition, this was early Win XP so no SP2.. continuing with errors after a first aborted installation cause the partition for bootcamp has an incorrect size, I restart a Mac session and I've deleted and created the Bootcamp partition. At restart I proceed to install Win XP without log in Mac.. During the install I've see that partition has an incorrect size but I accept these but in next step it requires to format.. so then i've abort installation... But when I tried to restart Mac partition has disappear.. and now there is no way to start Mac even the apple doesn't appear at grey screen.. any idea to solve that disaster? (not me, just only my mac he he).

Mac version is Snow Leopard but I can't boot with SL DVD, and with Leopard DVD Disk Utility doesn't recognise the partition and the only option is reformat..

Boot Camp and your woes
by mrmacfixit Forum moderator / January 7, 2010 2:19 AM PST

Boot Camp does not support and XP version less than SP2.

To get everything back into one piece again, Mac only, you will definitely have to boot from the Installation/Restore DVD and do a format and Install of the entire OS & applications.

To start from the Installation/Restore disk, insert the disk, shut down the Mac and then power it back up.
Hold down the "C" key at the first chime and keep it down until you see the Apple and spinning gears.

Let us know how you get on

The trouble is that I cant boot with nothing. I press Alt key and appears the mouse in the screen but doesn't appear any device, Installation DVD also, and a External HDD with a bootable Snow Leopard. Maybe could be the motherboard? The keyboard only response during a few seconds after that it blocks and no key works and Apple logo never appears (but the chord yes)

ZAP the PRAM by holding down the Command + Option + P + R keys at the first chime and hold them down until you hear the third chime.

None of all startup commands worked but I've fixed it. I've remove the disk from the computer and connected to a sata to usb interface. I've connected to another host and executed TestDisk tool. I've rewrited the founded map partition and then unmount and mount the disk again and that's it all of my data was there and was bootable again!
