First, download the image, http://mirrors.sohu.com/centos/7.0.1406/isos/x86_64/
Second, the next soft disk pass UltraISO, use it to open the mirror----start-to-write hard disk image. Note Select the USB flash drive. Making a Startup disk
The next step is to set the boot order of the machine, start the USB drive, and start the installation.
The online Daniel is very smooth, and I am very not smooth, encountered a variety of problems!
Two issues were encountered during the installation process:
[sda]asking for cache data failedThis problem has killed me, and I can't solve it now. Can only say, change a U disk. I solved this problem by replacing the ATA 4G with Kingston's 16G. Specific principle, do not understand.
Issue 2:warning:/dev/disk/by-label/centos-7-live-gnome-x86_64 does not exist
I analyzed the problem myself and could not find this directory. specifically to the CD LS in /dev/disk/by-label/ view, found only one file centos-7-li.
Very puzzled. How could that be. Rename via MV, failed (do not know how to proceed with the installation). Very puzzled.
Fahen, u disk inserted into Win7. Suddenly found that the startup disk, when produced by default, there is a disk name, just centos-7-li, rename, failed, cannot be renamed.
So, do not think too much, find the installation disk, all the. cfg suffix files, replace all the centos-7-live-gnome-x86_64 inside the centos-7-li.
Everything is good, finally can go into the installation interface.
Tragedy, come again.
Question 1: When space is allocated, it is only 3Mb. Open the System--tools (utils)->disk view.
With a disturbed mood, select a partition that does not have much data, and then in the corresponding box inside the '-' number, delete the partition, immediately found that the remaining space enough. Perfect solution.
Question 2: When hanging in swap, even if the space is enough can only 3M
I do not understand why, allocation/can 30GB, normal, swap is not. Refused to forget to allocate a swap, unexpectedly can. OK to delete the unqualified swap, the rest is OK.
(It is estimated that my hard disk is caused by discontinuous partitioning, do not go into the drill)
Finally, everything is normal.
Note Oh, do not rush to pull out the U disk after installation. Close the machine as normal path. Of course, this is a good habit. You can also pull out, generally do not have problems.
