Problems related to installation of CentOS 7 boot disk on USB flash disk

Problems related to installation of CentOS 7 boot disk on USB flash disk

1. First download image, http://mirrors.sohu.com/centos/7.0.1406/isos/x86_64/

Image introduction:

The first official text file. It also means 0_readme.txt, which probably means this (slag translation, but probably means there are still some ).

CentOS-7.0-1406-x86_64-DVD.iso: this image (DVD image) includes all the installation packages that can be installed with the installer, a recommended image for most users.

CentOS-7.0-1406-x86_64-NetInstall.iso: this image is used to install from the network or to rescue the system. When installing the system, the installer will ask where to get the installation package, which is recommended for users with CentOS local images.

CentOS-7.0-1406-x86_64-Everything.iso: this image contains a complete package for centos7 that can be used to install the system or fill in local images that require a dual-sided DVD or a USB flash drive above 8 GB.

CentOS-7.0-1406-x86_64-GnomeLive.iso

CentOS-7.0-1406-x86_64-KdeLive.iso (about 1 GB per size)

These two images are real-time images of CentOS, and different display managers (GNOME or KDE) are displayed for different names)

They can be used to explore or test the CentOS7 environment. They generally do not change the hard disk environment unless you install them in the live environment. This image must be installed on the installed system using yum.

CentOS-7.0-1406-x86_64-livecd.iso: this image is a bit like GNOMElive above, but there is no installation package like libreoffice, this image is small enough to easily burn on cd.

Second, the next disk uses ultraiso to open the image-> Start-> write to the hard disk image. Select the USB flash drive. Create a boot disk

Next, set the boot sequence of the machine, start the USB flash drive, and start the installation.

I encountered a variety of problems, but I was not doing well!

Two problems were encountered during installation:

[Sda] The problem of asking for cache data failed has killed me and I cannot solve it now. You can only change the USB flash drive. I switched from ATA 4G to Kingston's 16g to solve this problem. I don't understand the specific principle.

Question 2: warning:/dev/disk/by-label/CentOS-7-live-GNOME-x86_64 does not exist

I have analyzed this problem myself and cannot find this directory. Specifically go to cd ls to go in/dev/disk/by-label/view, found only one file CentOS-7-li.

Wondering. How can this happen. Failed to rename through mv (do not know how to continue installation ). Very puzzled.

The USB flash drive is inserted into win7. Suddenly found, boot disk, when making, the default disk name, exactly the CentOS-7-li, rename, failed, can not be renamed.

So, did not consider too much, find the installation disk, all the. cfg suffix files, replace all the CentOS-7-live-GNOME-x86_64 inside with a CentOS-7-li.

Finally, everything is normal.

Note: Do not rush to unplug the USB flash disk after installation. Shut down based on the normal path. Of course, this is a good habit. You can also undo it. Generally, there is no problem.
