Windows Blue Screen "unmountable_boot_volume"

Question

Windows Blue Screen "unmountable_boot_volume"

Hi!

I'm using Bootcamp on a MacBook Pro in order to install Windows XP Professional. After successful installation of Windows XP Professional (re-formated bootcamp partion by windows setup with NTFS file system) a Windows blue screen appears with "UNMOUNTABLE BOOTVOLUME" error. The Windows logo and progress bar was visible before the Windows blue screen appeared.

Does anybody know how I can tell Windows to be able to mount the boot volume? Is it a "volume rights issue"? What right settings do I need to set the partition?

Thanx for your help.

Hello,

As far as I know, there is no specific permission mechanisms for partitions.

You are sure that you installed a SP2 of Windows XP, and you installed Windows drivers provided with BootCamp beta or your Leopard DVD ?

You may have better luck posting to the Boot Camp Forum. But here's some ideas:

See http://support.microsoft.com/kb/555302/en-us In particular, boot off the Windows installation CD (hold down alt while booting, then select the CD) and enter the recovery console. Then do chkdsk /r and fixboot. Finally, exit

If that still doesn't help, boot back into Mac OS and open Disk Utility. Select your hard drive (not just the Macintosh HD Volume) and being very careful to not hit "apply" select the "partitions" tab and look at the bottom for the "Partition Map". Make sure it is GUID. It needs to be GUID to use Windows. It should be GUID if it is an MBP. If it is not GUID, unfortunately, the only method I know for converting it to GUID will effectively erase everything on the hard drive, including Mac OS.

Thanx for your respond.

I installed Windows XP by using Boot Camp Assistent coming with Leopard DVD. How do I install the Windows drivers provided with Leopard DVD?

If you could boot into Windows, you would install the drivers by inserting the Leopard DVD while in Windows. The installation should autostart. But since you were never able to boot into Windows, you never had the opportunity to install drivers.
