Uninstall Ubuntu GRUB problem

Run Windows Install CD → go to "recovery console" (or so) and use "fixmbr" command to install windows loader to MBR...

i did the fixmbr thing and still happends the same error 15 on grub. when i go to recovery console it appears 2 places where theres a windows instalation (i supouse one the real, one the cd), i did fixmbr on both, still got the same problem.

This is driveing me nuts

ive tried it all i think, i run the recovery mode, and did the fixmbr, did the fixboot, i did the bootcfg, i tryied to copy some files from the XP installer cd such as:
        COPY X:\i386\NTLDR C:
        COPY X:\i386\NTDETECT.COM C:

like its said here http://www.webtree.ca/windowsxp/repair_xp.htm#How%20to%20Repair%20the%20Boot%20Sector

but everything didnt work =(

That fixmbr stuff should work, but if it doesn't, there's probably no other way than to reinstall Windows.

had the same/similar problem .. here is what fixed my XP machine:

I deleted all UBUNTU partitions and repartitioned as desired and formatted. On booting, I had an option to boot Ubuntu or XP but had no Ubuntu to boot:

Fixes to the boot screen problem!!!!!!:

1. Boot from XP CD and into console mode. It defaults to C:windows.

2.Change to root dir C:

3. Execute 3 separate commands (enter after each):
fixmbr
fixboot
bootcfg /rebuild and I got result [1] below where I answered YES then nothing for "Load Identifier" then nothing for Enter Operating System Load Options: though I probably should have provided "/fastdetect" SEE BELOW:

"bootcfg /rebuild command scans the hard disks of the computer for Windows NT 4.0, Windows 2000, or Windows XP installations, and then displays the results. You can add the detected Windows installations.

You may receive a message that is similar to the following message:
Total Identified Windows Installs: 2

[1] C:Windows
Add installation to boot list? (Yes/No/All):
Enter Load Identifier: (Custom description for an operating system loading from the Boot menu)
Enter Operating System Load Options: (that is: /fastdetect)

THIS DID NOT COME UP:
[2] D:Windows
Add installation to boot list? (Yes/No/All):
Enter Load Identifier: (Custom description for an operating system loading from the Boot menu)
Enter Operating System Load Options: (that is: /fastdetect)

(enter bootcfg only for all available bootcfg commands).

Rebooted computer and NO boot screen!!!
