This should tell you the UUID of the block device, you will want to write this down. Once you find the /dev/ for the USB (for instance, if your system reads it as HDD, it might be /dev/sdd1), perform the command blkid on the device: blkid /dev/sdd1 Mount different block devices until you have found the one that contains the USB installer(this typically doesn't happen on true/Virt CDROM mounts). When the dracut shell becomes available, create a directory: mkdir /mnt/ This can often be caused by a mismatched label or /dev/sdXx root device when booting from USB. > dracut-initqueue: Warning: /dev/root does not exist > dracut-initqueue: Warning: Could not boot > sd 0:0:0:0: Assuming drive cache: write through
#Universal usb installer centos 7 install#
So I decided to try the 3rd option (the Troubleshooting -> one) with no luck I still cannot install this CentOS 7 and I got something like: > scsi 0:0:0:0: alua: not attached I have no idea what the fb is, and the installation process just stopped there. So I removed the quiet param and pressed CTRL x to start, then I got this: Linuxefi /images/pxeboot/vmlinuz inst.stage2=hd:LABEL=CentOS\x207\x20x86_64 quiet After that, three menu selections are presented:Īt first I decided to choose option 1 to let it display all its running messages, so I typed e and here is what I get: set params 'Install CentOS 7'
(My GIGABYTE motherboard uses F12 to choose a boot device.) I chose this: UEFI: hp v245o 1100, where hp v245o 1100 is the USB name, and I suppose this is a so-called EFI boot from USB.
#Universal usb installer centos 7 iso#
I downloaded the ISO image from the CentOS official website (the one named CentOS-7.0-1406-x86_64-DVD.iso) and then burned it onto a USB drive by using a tool named UltraISO.Īfter that, I rebooted my computer and pressed F12 to choose my boot device.
After hearing the news that CentOS 7 had been published, I decided to install it on my computer.
