Re: Partitions for a triple boot laptop
Why using extended (logical) from the start when you can use primary partitions until you have 3 of them. Only then start creating them as logical.
Partition #1, primary, 100GB for win7
Partition #2, primary, 100GB for win8
Partition #3, primary, 740GB for data
Logical 56GB for root
Logical 8GB for swap
If you want both win7 and win8 to be in the grub2 boot menu separately, you have to be careful before installing, otherwise windows combines the boot files and it's not easy to separate them later. Better to do it properly first time.
Install win7 as normal, but prepare the 100GB ntfs partition first. This way it will not create the small 100MB system reserved partition. The installer does that if you make the partition with it. If the partition already exists, it will not create the small one even if you format the previously prepared partition during the install. So, after the win7 install is done, you should have only one single 100GB primary partition on the disk. Make sure you check in Disk Management or from ubuntu live mode that this is true.
After that is done, create another ntfs partition of 100GB, use Gparted from ubuntu live mode and turn off the boot flag on the win7 partition. Turn on the boot flag on the new 100GB partition. Only after that start the win8 installer. That way it will keep the boot files separate putting them on the same partition as win8.
After that is done, create the data partition and then install ubuntu. That's it.
