Reload Ubuntu10.10 in Windows 7 with two systems

WinXP and Ubuntu have been used for a long time. Later, winXP experienced some problems and became slower and slower. Well, since the main operating system is Unbutu, in terms of user experience, win7 is undoubtedly a better choice.
After installing Windows 7, the startup items of Ubuntu are lost, and there is no Ubuntu installation disk of AJ brother in hand. You can only use tools to guide the installation.
A lot of related information on the Internet is from the old Ubuntu version. After struggling for a few hours, I finally got it done.
Required tools: 1. grub4dos 2. Ubuntu livecd or linux System in the U disk. I use KNOPPIX.
You can start it after you are ready.
1. go to linux in Ubuntu or USB flash drive of livecd and find: File System/boot/grub. cfg, open it in notepad, and write down the ubuntu startup command (there are many, we only need the first one );
2. Install grub4dos. After decompression, paste grldr, grldr. mbr and menu. lst to the X disk (the partition where win7 is located ).
3. Create boot. ini on disk X, and type [boot loader]
[Operating systems]
C: \ grldr. mbr = "grub4dos"
;
4. type the ubuntu startup information you noted down before in menu. lst (the system parameters are different for different computers)
Title Unbuntu 10.10
Root (hd0, 1)
Kernel/boot/vmlinuz-2.6.35-24-generic root = UUID = 1fe21987-20c1-4eb1-9a8a-c943e53b2f7e ro quiet splash
Initrd/boot/initrd. img-2.6.35-24-generic
Boot
5. Restart, select grub4dos, and select Unbuntu 10.10. The cute logo appears.
You can also directly use the grub4dos commondline to enter the system, but it is troublesome.
If the primary pe is used, grub4dos will be broken. Repeat steps 2-> 5.
That's it.
