For this case we shall have only one mount point /.Īfter this set the Label and Desired Capacity to whatever you wish. Depending on your requirements you might need to put the boot, home and root partition on different mount points. The next step is to create a mount point where the root partition will be installed.

You can also name your swap space to whatever name you like but a name like swap is more descriptive. Choose the File System for swap space as swap, and click on Reformat, though reformatting is optional. You can create a swap space from one of the partitions and set the desired capacity, which is dependent on the RAM you have. Next select the partitioning scheme to use for the mount points.

Click on the Installation Destination icon to change this to custom partitioning.Ĭlick on the hard drive you want to install CentOS 7 and under the Other Storage Options, choose I will configure partitioning then click Done. Be very careful about which output device you pick or you may overwrite something you did not intend to! On my machine I ran dd if= 5: Change The Installation Destinationīy default the Anaconda installer will choose automatic partitioning for your hard disk. If using dd for Windows, run dd -list and look carefully at the list of NT Block Device Objects and use the one that looks like \\?\Device\Harddisk1\Partition0 where the description is something like Removable media other than floppy.

If using a version of Windows newer than 7, make sure you unmount the USB drive first (formatting it prior to launching the disk copier is one way to accomplish that), otherwise Windows might refuse to write on the stick, bailing out with the "can't write to drive" error message. If you are experiencing problems installing CentOS from a USB stick and you used a utility other than dd on linux or the 4 listed above as 'working', then recreate it with one known to work before you try anything else. Confirmed as functioning correctly (2019) are:.Also Rufus does not work correctly if the wrong options are chosen so the tool is best avoided. Moreover, the CentOS 7 installer image has a special partitioning which, as of July 2014, most Windows tools do NOT transfer correctly leading to undefined behaviour when booting from the USB key.Īpplications known (2019) that do NOT work are: unetbootin, multibootusb and universal usb installler - do NOT use these.

Make sure you select as destination the device corresponding to the USB key ( /dev/sdz in the above example) and not a partition (such as /dev/sdz1)Įxactly the same method works for CentOS 7. This procedure allows a CentOS install without network connectivity and with no media other than a bootable USB device and the target system disk.ĬentOS release 6 (6.5 or newer) and CentOS 7 and 8 Many recent systems, particularly netbooks and small notebooks, may not have a CD or DVD drive and a network install may be difficult, impractical, or impossible, depending on network connectivity and installer support for the available network hardware. On linux, use the sha256sum command to do the same job. On Windows you can use the command certutil -hashfile c:\Users\JDoe\Downloads\CentOS-x86_64-dvd1.iso SHA256 to perform this checksum. You should check that your downloaded copy has a sha256sum that matches the published one to eliminate corrupted media install problems. These can be found in the release notes for each new version and also in a text file located in the same directory that you obtained the iso image from.

The CentOS Project publishes a full list of the sha256sums for each iso file.
