Triple Boot Install

Post by cycler2 »

I want to install Mint 14 on my Windows 7 and 8 dual boot computer. Both Windows systems are installed on separate partitions of an SSD, which is too full to accommodate Mint, but I have an installed hard drive with plenty of space and want to install Mint on an empty one Gig partition on this drive (which Gparted identifies as sda2). The install dialogue "sees" only the Windows 8 system and gives three options: Install alongside Windows 8, replace Windows 8 or "something else," which get me to manual partitioning. Can't use the first two options for guided install and I'm too new to Linux to try manual partitioning. Any ideas about how to get a "guided" install with this setup?
Thanks in advance for your help.

Only one GIg for Linux Mint? I assume that is a typo because that is not enough to do a full install of Linux Mint.

Anyway, let's get your hands dirty and "do something else" because what we need here is the manual partitioner.
You'll see something like this in the manual partitioner http://www.linuxbsdos.com/wp-content/up ... 00x394.png

Since you said that /dev/sda2 is your partition allocated for Linux Mint, well focus on that.
First click it and choose Delete to make a free space or unallocated space.
We need to create two partitions for this, one that will be assinged as the root partition or / partition and the other one is the swap.

Click /dev/sda2 and click Add. (on this part, I'll assume that it is a 10GB partition)
After clicking Add, in the dialog box that appears:
enter the partition size as 9000 since this value is in MB
Use as Ext4 filesystem
Mount Point, choose /
It should look something like this http://www.linuxbsdos.com/wp-content/up ... 00x294.png
Click OK

Now another partition will be created for the remaining 1000 MB.
Click that partition and hit Add again.
enter the partition size as 1000
Use as Swap area
It should look something like this http://www.linuxbsdos.com/wp-content/up ... 00x294.png
Click OK

Now back on the main partitioning screen again. Look at the bottom part,
"Device for boot loader installation" choose /dev/sda or your main harddrive partition to make sure that grub will handle all bootable OS in your system.

Click again the partition you assigned as the / partition and click Install Now. Now let the installer do its thing and everything should be OK upon reboot.

If for some reasons, you boot is messed up or won't boot at all, don't worry. You OSes and data partitions are still there. See this link and read about the 2nd option https://help.ubuntu.com/community/Boot-Repair
Basically you just boot into Live mode and use boot-repair to restore your bootloader.

Sidenote: Although I have tried this method a lot of times (and its relatively safe), you still have a chance to ruin all your partitions if you are not careful so be sure to have a backup of all your important data.
Goodluck and keep us posted on your progress.

This is probably NOT the new drive you installed! Look in the upper left of gparted for a small arrow and choose /dev/sdb (I'm guessing this is your newly installed drive)

What nerdtron posts is accurate ... there's an alternative to installing grub2 on /dev/sda (your Windows sdd). You can install grub2 on /dev/sdb and choose in BIOS to boot the second hard drive. On my installation If I do boot to my second hard drive via bios, grub2's os prober correctly identifies all 3 OSes.

Nerdtron and Pete,
Thank you both very much for your replies. Neretron--you have given me the courage (and knowledge) to try a manual partition. You were correct; I have a 1 Terabyte partition available for Mint, which I will partition. I have backed up the hard drive to which I will install Mint. Keep your fingers crossed!
Your helpful replies illustrate the welcoming and patient nature of the Linux community. Thanks again.
