So I'm trying to do a dual boot gentoo install on a hardrive where Windows 8.1 is currently installed on. I followed an online article on how to prep your machine
For a Windows 8 and gentoo dual boot installation. In the article it said to shrink the Windows partition. Did all the required steps and made the unallocated space into a new volume :D.

But I stopped there as I had to run an errand. Now that I'm trying to finish the install today By following both the original handbook and Sakaki's install guide it seems that the space I made by shrinking the Windows partition needed to stay as an unallocated/unused space.

Can I just delete the volume, revert it back to an unallocated space and continue with the install or is there a way to partition that partition/volume for gentoo, like this for example?
/dev/sda5/usr
/dev/sda5/home
/dev/sda5/tmp

Ok so I left the space as unallocated and continued with the hand book. My hard drive is gpt and I'm trying to create the BIOS boot partition. In the handbook it says to make a small partition of 2mb. I researched a bit and found that a bios boot partition is recommended to be of 300mb to 500mb.

I use the parted script and the "mkpart primary 1 500".

I then get a warning:
Code:
(parted) mkpart primary 1 500
Warning: You requested a partition from 1MiB to 500MiB (sectors 1953 . .976562).
The closest location we can manage is 1.00MiB to 1.00MiB (sectors 2047..2047).
Is this still acceptable to you?
Yes/No?

I think you're telling it to put your partition before your Windows partition, and it's telling you there's no room there. Don't do that. Put them after.

Use the System Rescue CD or similar if you are confused. They have graphical partitioning tools that should help you visualize what you are doing and not destroy windows. That can be expensive if you don't have proper backups (you do, right?) The rescue CD can substitute for the install media for the entire install. It is literally a drop in replacement.

I'll give the rescue cd a shot.

And yes I made a system recovery cd but no backups of personal data as there's really nothing that needs saving.

It's often a good idea to leave a Windows installation (particularly a modern installation) alone,
except for shrinking the partition, and boot Grub via the Windows boot menu which you can
edit with BCD Edit. Worth checking out before you go any further.

Sure, wait two days, until he's probably ass-deep in his install and irretrievably committed to his chosen path, and THEN give this little gem of wisdom. :roll: :lol:

I'm actually done. Or sort of, have some doubts on some parts of the install specifically with the kernel but since no error messages or crashes have surfaced I just continued.

I'm right on the umount and just about to reboot. I will look into grub if I'm able to boot again.

Also instead of opening another thread I think it'll be best to ask here. I'm trying to umount the partions but I get an error saying that the mount points are not found. A picture here.

Seems like I just installed gentoo nowhere...

Update:
So I decided to reboot anyway. Can't mount anything. Keep getting a no such file or directory.

Also any way to check the install for specific errors and maybe fix them instead of trying to do a Complete reinstall. Or what would be the best approach to do a complete fresh install.

Boot off the Sysrescue CD and check that the partition layout is the layout you expect.
Try mounting the partitions, and see if they have the contents you expect.

Generally it's easier to fix an install than re-install, unless things have got very strange.
