I know this place maybe isn't the best place to ask for help with this specific question, but I guess you can help.
I have a UEFI system with partitions arranged as follows:
#
# /etc/fstab: static file system information
#
# <file system> <dir> <type> <options> <dump> <pass>
# /dev/sda2
UUID=1839555a-70c8-4fec-8938-cfd7a16ecc6d / ext4 rw,relatime,data=ordered,discard,noatime 0 1
# /dev/sdb1
UUID=6d26afd2-cc3e-44a4-b5bd-ea209cd4343d /home ext4 rw,relatime,data=ordered,discard,noatime 0 2
# /dev/sda1
UUID=7628-D37A /boot vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 2
# /dev/sdb2
UUID=f37bdb49-1d0f-4455-8f2d-559b923bfb40 /var reiserfs rw,relatime 0 2
# /dev/sdb3
UUID=96c1dbed-cf83-4a2e-9fc2-dcd9fa01a6bb /tmp reiserfs rw,relatime 0 2
(note that this is my system's fstab)
now, here is some info about how these partitions are arranged and their sizes: hardware:
SSD - 60Gb
HDD - 500Gb
/ - about 20Gb on the SSD
/boot - about 1Gb on the SSD
/home - about 100Gb on the HDD
/var - 10Gb on the HDD
/tmp - 1Gb on the HDD
That means that I have about 389 Gb of empty space on the HDD, I want to use 100~200Gb from those to install Windows for games but I also want to keep some space for installing Gentoo.
What would be the easiest way to install Windows? I don't want to put it on the SSD and won't use it for anything other than gaming, and I don't want to ruin my current Arch setup.
Also can use the same /tmp partition in Arch or Gentoo? or it isn't possible? Same question but with a swap partition (that is if I eventually have to use one).
BTW what about using a VM? is it worth it? I have 8Gb RAM and can easily get more...
And do you have any other recommendations?
