Hi,

I have downloaded both the 64bit DVD iso for centos 6.2.
Now when there was a single iso file - I could
perform the installation from the grub prompt.
That can also be done now though the installation
is failing to notice the second dvd iso. How can I make the
installer take note of it despite lying in the same directory as the
first iso?

Can anyone provide some sort of help in this regard?

Thanks in advance.

Not sure what GRUB has to do with it. That is out of the picture once the installer starts. Few installations require both ISOs. I'd just do an install from DVD1 and add anything else later.

If I have Fedora or Ubuntu on a disk and I want to add Centos6.2 (I write software and want to test with each version), my concern is that grub 2 is compatible with Fedora and UBUNTU, but if Centos installs with Grub 1, then the other two operating systems will not be available.

If I knew Centos6.2 was using Grub 2, there will be a non-issue. My prior Centos version was 5.1 and used grub version 1.

I have used every search engine, including the search in this community, and also the announcements about Centos and not one line about the grub version is mentioned.

Ah, I can answer that one.

When installing CentOS, be sure that it puts grub in its root partition, rather than the MBR. That is, if you install CentOS on /dev/sda3 when you install grub, there will be an option to put grub there, rather than in /dev/sda.

Afterwards, if you're booting from Fedora's grub2, I ignore that 40_custom or 41 or whatever it is. Instead, I create a file /boot/grub2/custom.cfg It would read




Note that although grub2 still counts drives from 0--that is /dev/sda is hd0, it counts partitions from 1, so /dev/sda1 is hd0,1, unlike legacy grub, where it would be hd0,0.

I have a page on the Fedora version at

If Scott's helpful reply is not sufficient please start a new Topic for your issue to get the attention you need, providing a link to this one if required for context. (And to become an accessory after the fact to the hijacking - CentOS-6 uses GRUB-1. )

@Scott - Another good page from the computertaijutsu - just bookmarked it. Thanks.

Thanks Phil--I hadn't realized it was a hijacked thread, just saw the grub2 part, which I have learned about.

My page will probably be dated soon, but at the time, there was almost nothing out there about Fedora's grub2, only Ubuntu's, and there were slight differences.
