The specific actions are as follows:
1. Prepare a U disk, do not need to be too big (of course, the capacity of the big point is no problem, the rest of the space can continue to use), the contents of the first back up;
2. Use the HP USB drive format tool to make this USB disk as a MS DOS boot disk;
-Format and create MS-DOS boot u disk
3. Create a new folder in the U disk boot, download grub4dos, will download the grub4dos after decompression all put into the boot folder, while the folder name to GRUB (short good remember to use), at this time Grub.exe path for U disk: Bootgrubgru B.exe;
4. Edit the U disk by using a text editor (such as Notepad): Bootgrubmenu.lst The file (probably the 10th line) (The following is a comment after the # number)
The code is as follows |

Kernel/boot/vmlinuz-2.6.37.6-0.5-desktop # If the kernel is upgraded or is not OpenSUSE 11.4, the version number may need to change accordingly Initrd/boot/initrd-2.6.37.6-0.5-desktop # ditto Boot savedefault–wait=2 |
and save it.
5. For convenience, create a batch file in the root directory of U disk to start grub. Create a text file in the root directory of the U disk and write the following command:
@echo on
C:bootgrubgrub.exe
The text file is then renamed Grub.bat (Note that the suffix is changed) (the letter is C because the disk is the use of U-boot after booting the U disk is a C disk, which is used above (hd1,5) reasons).
6. You can now use a U disk to start OpenSUSE or Windows 7 (by the way), U disk startup after the input grub.bat and return to see the boot menu.
It should be noted that every time you upgrade the Linux kernel, you need to modify the version number in the Menu.lst
