2nd linux non-multiboot

Post by Gorgar » Thu Mar 08, 2018 3:44 pm

Dear community!

I am writing to you from Germany and hope to get my point accross.

I am running Linux mint 17.3 KDE 64bit on a multiboot machine.

For emergency and testing, i would like to install another linux on my second internal hdd, without adding it to (and probably messing with) the bootloader/MBR of disk #01.

It would be o.k. if i could access it thru <F12> on startup only.

Do i have to unmount or hide the windows partitions before installing?
What else is there to consider?
Maybe a virtual machine would be the better idea?

Thank you for your help.

A first useful remark might be that a Live Linux DVD/USB also makes for a fine emergency system; depending on what you are testing not necessarily a fine testing system. Virtual machines make for neither generally.

But other than that just install the second Linux system's bootloader -- grub supposedly -- in the MBR of HDD #02; on /dev/sdb rather than /dev/sda if disks are connected in a standard manner. The install itself would at least in the case of Linux Mint not change anything on HDD #01. Running sudo update-grub from either Linux system would include both Windows and the other Linux system as options; that'll be fine though: it's a just a configuration file change. Booting the second disk with F12 would allow you to boot into the second system's grub, and I have used a second system's grub as an "emergency" grub copy at times, but generally you'd just the first Linux system's grub to boot any system.
