Hi guys,
When I boot from my Gentoo CD, it just hang at the line "Mounting dev/sda3" and doesnt give any error message. What should I do now?
I have Windows 8 and Mint installed in the system, here is the partition list:


Code:
   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *          63   225279494   112639716    7  HPFS/NTFS/exFAT
/dev/sda2       225279495   286712054    30716280    7  HPFS/NTFS/exFAT
/dev/sda3       286712116   976768064   345027974+   f  W95 Ext'd (LBA)
/dev/sda5       286712118   327661739    20474811   83  Linux
/dev/sda6       349081600   430043135    40480768    7  HPFS/NTFS/exFAT
/dev/sda7       430044048   976768064   273362008+   7  HPFS/NTFS/exFAT
/dev/sda8       327663616   349079551    10707968   82  Linux swap / Solaris

btw, is it normal for Dumpe2fs to report "magic number"/"could not find valid superblock" when checking my NTFS/extended partition superblock?
Thanks

I would strongly suggest using SystemRescueCD as an installation medium, if the Gentoo minimal iso does not boot for you. You can follow the few additional steps in the Alternate Install Guide in addition to the manual. This is how I (and many others) install Gentoo. I've never actually used the minimal cd.

You have two options. Option 1) If you are not going to change mint, use mint. By this I mean you will not change the size of the Mint partitions. All you may need to install is chroot.
2) System Rescue CD, as above. One minor flaw with the above. the system rescue CD does NOT need any of the extra steps. It is a Gentoo based distro, and therefore is the same as the Gentoo min. It just comes with a few extra programs, including X and Firefox.

There really is nothing sacred about the Gentoo min. It is a linux, like any other.

I always suspected that those extra steps were not necessary, but always did them out of habit. Thanks for the correction!

No matter what installation media to use. The only limitation - it should be the same architecture - x86 or x86_64. All you need is boot into terminal.
If you not planning to remove your Mint during Gentoo installation (and Mint is the same architecture x86/x86_64 as Gentoo) you can install Gentoo from Mint instead of installing from any CD image.
Just boot into Mint, switch to terminal (Alt+Ctrl+F1) and follow Gentoo Handbook. By the way you can read handbook from Mint browser. It is very handy, just switch back to Mint by Alt+Ctrl+F7.

BTW, why Gentoo Handbook doesn't described this installation way?

Thanks, I have just installed Gentoo in Mint. Btw, there is no need to install the Bootloader, just run update-grub within Mint :)
The method is mentioned in Gentoo handbook actually :)
