How to install CentOS

Complete output information reference:

Here, CentOS will start.

Here, if vmlinuz and initrd.img are decompressed (isolinux), then write:

Note: root (hd0,2) is setting the current root Directory location, hd0 represents the first hard disk, 2 is the device code (partition, the first C drive is 0, D drive 1, E drive 2, etc.), representing the fat partition where vmlinuz and initrd.img are placed. If you can't correct it, you can modify it. After root (hd0, 2) enters the carriage return, you will be prompted to similar:

If there is no such partition, you will be prompted: Error 22: No such partition

If there is this partition, you will be prompted: Filesystem type is fat, partition type 0x0C

The subsequent instructions can be input continuously. It doesn't matter if you input the error. If you are wrong, you can't enter the CentOS installation program. OK will start.

Method 2: Add menu.lst in advance, and restart the machine after modification.

menu.lst can be extracted in the grub archive, copied to the C:\\ root directory (can also be placed in /boot/menu.lst, can also be placed in /grub/menu.lst, Grub automatically searches for these three directories when it starts.)

Modify menu.lst content:

If vmlinuz and initrd.img are decompressed in the whole directory (isolinux), write it as:

Second, CentOS Ultimate Installation Method

This method is compatible Better, but need to involve partition operations before installation, pay attention to protect data. Tianyuan also installed CentOS-6.0-i386-LiveDVD on the DELL machine. According to the above method, the installation always prompts:

signal caught! boot has failed, sleeping forever

error, so change Into the binDVD version, but the original image is only about 1.6G, and CentOS-6.0-i386-bin-DVD.iso has a pothole of 4G, FAT32 can not put it, and there is no way to engrave, so "self-made" the following method :

1. On XP, reserve a free partition for the CentOS (delete partition), use the partition tool to create a 5G EXT3 partition at the beginning of the free partition, and the remaining space can be created as one. EXT3 partition (the actual installation can also be customized, it seems to have to be created first, otherwise it seems to prompt the error when installing, too many times to forget the turn), note that the start is not the last, if the ISO partition is placed last , then the following error will be prompted when actually installing to the manual partition:

Could not allocate requested partitions:

Partitioning failed: Could not allocate

partitions as primary partitions.< Br>

Not enough space left To create partition

At this point, the last EXT3 partition number has changed, so the installer can't find the original copy of the installation file. So it is better to divide the partition first (Tianyuanguang tried it back and forth several times here).

2, then find the Ext2fsd tool, modify the load to write the drive, and copy the 4G file (originally placed on the NTFS partition).

3, extract the ISO isolinux directory and image directory (less one can not, if there is no image, the installation will appear /images/install.img look for errors), the same copy to the EXT3 partition root .

4, the subsequent steps are similar to the above, but do not know the ID number of this EXT partition when setting root, so use the following statement:

The above Find statement, if you know which drive, you can also directly root (hd0, x) Set, if you don't know the find command, then use this to look at:

Output (hd0, 4), OK found. Root runs wood problem.

5, automatically start into the installation interface, the notes are as follows:

6, if 4 choose Method 2 above, enters GRUB and automatically enters without editing.

Special reminder:

When installing the "Which type of installation would you like?" setting interface,

, anyway, you can confirm it again, otherwise, install The program did not repent, and began to install directly.
