Back in the early days of Windows 7, usually there were only three primary partitions (system, OS partition & Recovery). A year or so later, various OEM added a 'Tools' partition, have seen many HP models with this & to be honest, am not exactly sure what it's for.
Cat1092 & Pcpunk,
This is very interesting! I guess mine was missing this because it's an old. Also glad I listened to everyone telling me to stay away from HP!
Am I going to have trouble with this laptop when I try to wipe the drive and reinstall Ubuntu someday? Are the partitions that grub2 created permanent? I don't think I want an ntfs formatted partition there forever.
Ubiq, to answer your questions:
1) No, you won't have any issues with wiping the drive & installing Ubuntu, None at all, as long as your computer meets the requirements of the OS. Most any computer since the mid to late Vista years will run today's titles.
2) No partitions are permanent, with a partition tool, like GParted, a tool that that's optional on many Linux distros, can be installed from the Ubuntu Software Center will delete any you wish. You can also download & create a bootable CD ISO image (recommended), or the ISO will work with bootable apps like Rufus to create a bootable Flash drive to accomplish the same w/out the need of a CD. You may also use any Linux install media on hand to do the same with, these has GParted built in.
3) This includes the NTFS partition that you may not want there forever.
Though you may desire to create your own Topic over these issues when the time arrives.
Hope that this answers your questions & we're happy to have both you & jargos in our Linux community.
