BT5 hard disk installation method

This is an installation method using Ubuntu hard disk. BT5 is also applicable (on Windows XP, Windows 7 should use bcdedit to set the startup item, but I have never tried it ).
My computer does not know why, does not support U disk boot, the optical drive is broken, so the above system basically uses the hard disk installation method.
I used to install BT5 on my mobile hard drive. The method is as follows:
1. Put the BT5 ISO file and grub4dos in the C-drive root directory.
2. Extract two grldr files and menu. lst files from the grup4dos package and put them in the C-drive root directory.
3. Extract the casper folder from the ISO of BT5 to the c root directory.
4. Open the case folder under the C drive and copy the initrd.gz and vmlinuz files to the C drive root directory.
5. Edit the menu. lst file and modify it as follows: www.2cto.com
Title BT5 installroot (hd0, 0) kernel/vmlinuz boot = casper iso-scan/filename =/BT5R2-GNOME-32.iso text splash vga = 791 -- initrd/initrd.gz boot
Copy code
6. Open the boot. ini file in the root directory of the C drive. This file is read-only hidden by default in xp.
Modify timeout = 10
Add the startup Item c: \ grldr = "install BT5" at the end, as shown below:
 
Timeout = 10
C: \ grldr = "install BT5"
Copy code
7. Restart your computer and select install BT5 from the boot menu to go to The BT5 boot screen.
8. At this time, it will be stuck in the picture of BT5 (which is my case anyway). Press the arrow keys and the system starts to start.
9. After the command is successfully started, enter the command prompt interface.
10. the startx startup graphic interface.
11. The subsequent processes are all the same ....
 
PS: If you want to install it on a mobile hard disk, remember to select the installation location of bootloader in the "advanced" option and install it in the mobile hard disk partition.
