Problems with linux installation in a notebook (solution)

Problems encountered when installing linux in a notebook (solution)-Linux general technology-Linux technology and application information. The following is a detailed description. I have been installing linux in a notebook for the past few days. If I try to install it, I still cannot install it. It is not stuck when the progress bar is reached, or it is stuck when detecting system hardware, hard Disk installation has been tried)
Finally, we have solved the problem and share it with you:
I installed Ubuntu. In fact, the same is true for Fedora and debian. After the language is selected for installation (that is, the first step for installation), ubuntu9.04 is based on F6, press enter to select acpi = off noapic nolapic. It is best to select all three. If there are not at least the first two, let's talk about it here. Some forums say that the code "acpi = off noapic" is added at startup, in fact, it is selected by keyboard instead of typing. Then select esc and install it .... There is another important point here. It is best to unplug and install all your external USB devices. Otherwise, the chances of getting stuck are relatively high. Even taking a lot of detours >_<.
After the installation is complete, add acpi = off noapic nolapic to the kernel line in gedit/boot/grub/menu. lst.
Otherwise, even if you have installed it, the restart may fail ~!
Note: the possible situations of getting stuck do not occur at the same time.
