HiI've installed Centos 6.3, only to find that after POST, GRUB acts as if the centos install doesn't exist. Centos is certainly there on the 26G hdd partition. I instal... [by Tabby]
So the setup is simple....
sdb has one Linux partition with centos 6
sda has one Linux partition with centos 7
Centos 6 was installed in sdb.... only one partition, no swap, no /home just /
Centos 7 was installed in sda.... only one partition, no swap, no /home just /
I updated centos 6... and of course it install a new kernel....
then I updated centos 7...
I was trying to dual boot my system with Centos 6.5 and Win7 using usb stick.
Win7 was already installed.
I created a partition of 100G from Win7 for CentOS 6.5.
I created a bootable disk using fedora live-usb creator for centos 6.5.
Two options are there for booting from USB:
2) UEFI: USB
I tried both.
