Hi.

I'm about to make a dual-boot computer with one SSD drive and two HDDs in hw-raid 1 mode.

This is what I'd like to do:

- dual-boot Windows 10 (when it is launched) and Ubuntu 15.04 from a single SSD drive, store important userdata on raid1 HDDs.

Questions:

- is it possible to boot Windows 10 and Ubuntu 15.04 from same SSD?
- which OS should I install first, Windows 10 or Ubuntu 15.04?
- when setting up system-partitions, what should I take into concideration?
- should GRUB be in MBR or should the Windows boot loader be in MBR?


Thx,

SSD is great, but does not change the multiboot landscape.
All of the documentation on multiboot using an HDD applieds to SSD except the performance parameters based upon underlying hardware and behavior.

I would first boot with a live-CD to pre-partition the SDD space. If the Win10 install will honor it (I have not tried it with Win10 myself yet) this makes life much easier: no need to reduce the windows partition later, if it starts at the right size.
Install Win10 first. Then, when it is as you like it, install Linux on the other SSD partition. The grub bootloader handles both Windows and Linux better than the Windows bootloader handles linux.

I agree with all of wpeckham's recommendations. Please consider updating the thread with the results. I am interested to know if there were any glitches or if the recommended course, exactly what I'd follow, just works.

It's no different than setting up dual boot on any other machine. Partition the drive first, then install Windows. If Windows will let you install to your desired partition, you're fine, if not just let it take the whole drive and then shrink it afterward. Then install Linux in the remaining space, the bootloader should auto-detect your Windows installation and add it to the boot menu.

The RAID might be more difficult. You said it's a hardware RAID, what RAID card are you using?

You'll have to redo it if you put linux on now. Not a big deal just time consuming.

I'd assume you'd have to save the 100m and the normal partition for windows but as in windows 7 there was a way to erase it after.

Could just get the preview of 10 and install it now first and then linux. When offical 10 arrives then load it over preview.

Hi.

Thank you all for the information.

@wpeckham, then I will follow basic dual-boot procedures.


@rtmistler, I will update this thread after the 29th of July.


@suicidaleggroll, I will be using one of the RAID devices found on the Asrock Z77 Pro4 motherboard. Quote from Asrocks site:

- 2 x SATA3 6.0 Gb/s connectors by Intel® Z77, support RAID (RAID 0, RAID 1, RAID 5, RAID 10, Intel® Rapid Storage and Intel® Smart Response Technology), NCQ, AHCI and Hot Plug functions
- 2 x SATA3 6.0 Gb/s connectors by ASMedia ASM1061, support NCQ, AHCI and Hot Plug functions

Which one might be better to use for Ubuntu? Intel's maybe?


@jefro, will wait for gold version of Win10.

As I suspected, that's not hardware raid. You will never find a hardware raid controller built into a consumer grade motherboard. That is what's affectionately known as a "fake raid". All of the drawbacks of both hardware and software raid with none of the benefits of either. If you don't want to run a real hardware raid ($300+ dedicated PCIe controller card), then leave that off and use software raid. You'll only be able to see it from either Linux or Windows though, they can't "share" a software raid like they can a hardware raid as far as I know.

Thanks for the tip, I will leave raid off and do the following setup instead,

- 1 ssd, 2 hdds (no raid).
- win10 and Ubuntu on ssd, 1 shared hdd for user data, 1 shared hdd for backup of important files with Déjà Dup.
