How to create 3 boot partitions and make an operating system on each one

[DerGillster]

For computer repair I am assigned to create 3 partitions and install an operating system on each one. I know I have to go to disk management and set it up. But what do you do after creating your drives? How do I switch between the hard drives to install operating systems on each one? My instructor tells us having to push delete when the computer is restarting, but I haven't been clear on why we do that.

If you install them on the same hdd, once you've installed three of them and reboot, a bootmenu will come up (or should).

Then you select what OS you want to boot into

If theyre 3 different hdd's make sure all 3 are connected when you install whatever OS.

Just remember WHAT hdd you've installed whatever on. Before you install the next OS. Otherwise, you may format the same hdd again

DON'T disconnect / remove any of them otherwise you'll have to go into the BIOS all the time to change the bootdisk. Or if the system supports F8 (you'll have to select a bootdisk).

And as above once all 3 have been installed, you should get a menu.

You'll have to press delete (if all 3 hdds arent connected when you install the OS) to get into the BIOS, to change the bootdisk

So your instructor is wrong if you do it the right way. You wont have to press del after restarting at all

And no you dont have to use disk management. The windows DVD/CD (its setup screen) can also delete / create partitions. And you can also format the hdd here. Then install windows

The only time you may have to format a hdd on another system, (or in disk management). is if the hdd is over 2.1/2.2 TB. Since you have to have a system that supports UEFI. And the hdd will have to be formatted in GPT.

So you can use all of the hdd

And to switch between the 3 hdd's (to install windows on it) in the setup screen, select the hdd then partition / format / install windows on it
