Solve the Problem of crash during Ubuntu9.10 Installation

I want to try Ubuntu9.10 recently. I didn't expect to install Ubuntu9.10, But I encountered a lot of trouble. After LIVECD is started, the system will crash in a few seconds. Whether it's using Ubuntu9.10 official ISO, or using LinuxMint8 or LinuxMint8KDERC1 Based on Ubuntu9.10. After searching online for multiple days, we finally found that this problem was caused by ACPI. The self-starting disc will automatically use ACPI, even in the GRUB menu. l

I want to try Ubuntu 9.10 recently. I didn't expect it to be difficult to install Ubuntu 9.10. After LIVECD is started, the system will crash in a few seconds. Whether it's Ubuntu 9.10's official ISO or Ubuntu 9.10-based Linux Mint8 or Linux Mint 8 KDE RC1. After searching online for multiple days, we finally found that this problem was caused by ACPI. The self-starting disc will automatically use ACPI. Even if the acpi = off parameter is used in the GRUB menu. lst, it will also crash. There is a solution on the Internet. I tried it and it worked. The method is as follows:

Boot with a CD or hard disk. Do not enter the normal startup mode when starting, but enter the "recovery mode ). If it is started from the hard disk, in menu. lst, write as follows:
Title Install LinuxMint-8-KDE-RC1.iso
Rootnoverify (hd0, 1)
Find/LinuxMint-8-KDE-RC1.iso
Kernel/vmlinuz boot =/casper iso-scan/filename =/LinuxMint-8-KDE-RC1.iso ro single
Initrd/initrd. lz
Note that ro single is used later, so that it will start to the repair mode.

When starting in repair mode, a menu is displayed, and the last item is selected:
Root Drop to root shell prompt
The command line is started.
After entering the command line status, enter the following command:
# Cd/etc/rc2.d
# Mv S99acpi-support K99acpi-support
# Update-rc.d acpi-support defaults
The last command prompts you not to worry about it.
Then enter the command
# Startx
Start the X Window.
Try again after you see the graphic interface. There should have been an "Install" icon on the desktop, and it will not be visible now. But it does not matter. You can choose from the system menu.
If it is started from the hard disk ISO file, open the terminal before installation and enter the command
# Sudo umount-l/isodevice
Run the installer and follow the instructions.
During the installation process, it is recommended that you do not use the CTRL + ALT + F1 console to switch the screen in disorder :)

After the installation is complete, you need to change the grub startup configuration before restarting the system for the first time. You should be able to change it directly in the LIVECD startup status (note the partition of the file to be changed ), you can also start to the repair mode and enter the command line before modifying. Otherwise, the system crashes after startup.
# Sudo vim/boot/grub. cfg

Add the acpi = off parameter to the startup Item of Linux Mint 8 Helena-kde ce:
Menuentry "Linux Mint 8 Helena-kde ce, linux 2.6.31-16-generic (/dev/sda9 )"{
Recordfail = 1
If [-n $ {have_grubenv}]; then save_env recordfail; fi
Set quiet = 1
Insmod ext2
Set root = (hd0, 9)
Search -- no-floppy -- fs-uuid -- set 897e6c78-835e-4dec-91e0-62312b49d348
Linux/boot/vmlinuz-2.6.31-16-generic root = UUID = 897e6c78-835e-4dec-91e0-62312b49d348 acpi = off ro quiet splash
Initrd/boot/initrd. img-2.6.31-16-generic
}

With this way to install the LinuxMint-8-KDE-RC1.iso successfully, installed after running well.

I want to install Ubuntu 9.10/Linux Mint 8. It should also be possible to solve ACPI's crash problem in this way, because they use the same underlying layer, but I did not try it one by one.
