Thanks, the disk shrinking worked.

The installation went well, thanks. The remaining problem is that W8
boot manager partition on the SSD /dev/sda2 has the boot flag set (not
changeable from Linux, is it from W8?) On the SSD the Linux partition
is /dev/sda5, which I made bootable (also UEFI boot). However, even if
grub is written to /dev/sda no grub menu appears, and only W8 starts up
every time. Additionally, booting from the HDD does not seem to be
possible, at least within W8. How to access the UEFI boot manager, can
it be enabled by a BIOS setting change?
