Boot loader Grub: how to repair, adapt or remove it - Easy Linux tips project

With the free Ultimate Boot CD

10.4.
No installation CD or DVD of Windows? Then you can restore NTLoader
also by using the free Ultimate Boot CD (UBCD). You can download it here.



Pick the .iso of the stable version, and burn it on a CD as a raw image.



Boot your computer from the UBCD (make sure that the CD drive is first in the boot order in the BIOS).



UBCD contains several tools to restore NT Loader in the MBR. I'll describe the use of one of them.



Select HDD in the menu, then Boot Management, then Super Grub Disk. Then
press Enter again, in order to start the Super Grub Disk. Then you
choose:

Win => MBR &  !WIN!   :(((((((((((((((((((((((((((((((((

Press Enter.



By the way: the multitude of arches (sigh) isn't my idea, but the idea of the maker of the Super Grub Disk...



Now you're done! Reboot your computer normally. Your computer should boot up Windows now.



With a USB memory stick

10.5.
Finally, you can also use a USB memory stick for this job. It takes
three applications: Unetbootin, FreeDOS and Testdisk for DOS.



a. First download Unetbootin and use it to make a bootable USB memory stick. Choose Freedos when prompted for a distribution to install on it.



b. Download Testdisk for Dos/Win9x (so don't select the Windows version!).



c. Unzip the files testdisk.exe and CWSDPMI.exe, and put them on the bootable memory stick (not in a folder, just straight on it).



d. Boot your computer from the memory stick. At the Default window, simply press Enter.



e. Now FreeDOS is being launched. Choose:

FreeDOS Safe Mode (don't load any drivers)

Press Enter.



f. Then type: C:

Press Enter.



g. Now type: testdisk

Press Enter.



h. Select [No Log]

Press Enter.



i. Select the hard drive concerned: usually the second option (the first option is the memory stick itself!).

Press Enter.



j. Select [Intel]

Press Enter



k. Select [MBR Code] and press Enter. When prompted, type y (yes) and press Enter again.



Now you're done! Reboot your computer normally. Your computer should boot up Windows now.
