Raid 0 won´t show in bootable devices

Found the culprit!

 

There was no EFI partition on the RAID0!

 

So i went into recovery mode and followed these instructions:

 

Spoiler

if you are not sure where windows is installed use bootrec /scanos and keep the drive letter in mind.

 

X:\windows\system32>diskpart

DISKPART> list disk

DISKPART> sel disk {X} (your RAID disk)

Disk X is now the selected disk.

DISKPART> list part

DISKPART> sel part {Y} (your main partition with enough storage space)

Partition Y is now the selected partition.

DISKPART> shrink desired=1024

DiskPart successfully shrunk the volume by: 1024 MB

DISKPART> create partition efi size=260

DiskPart succeeded in creating the specified partition.

DISKPART> format quick fs=fat32

100 percent completed

DiskPart successfully formatted the volume.

DISKPART> exit

Leaving DiskPart…

X:\windows\system32>bcdboot c:\windows
Boot files successfully created.

 

Now the pc should recognise the RAID in BIOS and boot properly.

Hello guys,

 

i had to change to a new motherboard today because my old one died. (or the CPU idk.)

And before anybody comments that a RAID 0 as main partition is stupid, thanks, yes i know and i was dumb when I made it this way.

 

Everything went fine, except i can't boot into Windows.

 

I have a:

Asus Maximus XII Formula

Intel i9 10900k

2x m.2 970 evo 500gb

 

My old setup was:

Asus Maximus IX Formula

Intel I7 7700k

Same SSD's

 

Now the problem is that I set up the RAID 0 the same way as on all devices ( CSM off, Intel Rapid store on, etc...) but the raid device does not show up as bootable device, although in the intel rapid store page it states that the raid is detected, running normal and is bootable.

 

I have tried about everything.

Is there a way to make this work or do i have to delete the raid and start from 0?

 

Thanks in advance

You don’t want to boot off it anyway.  Host of problems.  I suggest setting up an SSD for OS boot.  Can you read the thing even if you can’t boot off it?


Life is like a bowl of chocolates: there are all these little crinkly paper cups everywhere.

Moving Raid arrays between motherboard with different controllers may not work at all. I have always had Raid0 on the PCs i build myself. 

 

Now i have Raid0 2xSSD=500gb for booting windows and Raid0 2xHDD=1TB for games and programs. I never expect to move my arrays in a different PC and have them actually work. it may happen but its a long shot .

 

Boot from another HD to see if you can even detect the array backup your important data, format, rebuild the array and install windows from scratch.

 

You have a different PC now and you expect it to boot with the old windows you had on the previous PC sometimes the differences in hardware are so many that windows can not even boot.

You might need to install the boot loader again.

 

Make a backup first though.

i simply can't boot from it because it wont show in the boot option priorities or overrides as if it was detected but the bios thinks its not a bootable device

Do a backup first.

 

Then try doing boot repair in windows, Its on he installer, then cmd. I forget the exact commands, but there are guides on google.

*update

 

i don't know how i managed it to make it work, but at least i know i dont have to make a new windows install (for now) 

 

so how did i do it

first i made a new windows instalation on a second ssd then got in the cmd in the advanced restart options

i tried using a few guides but this command made it work 

bcdboot c:\Windows /l en-us /s V: /f ALL

 

but now comes the weird stuff

the bios still can't recognise the raid it finds only the newly created windows ssd

but after the bios phase when i press f8 to get to the windows startup bootloader i can select 2 partitions (the one with the new windows and my raid) 

 

so now i am more confused than before
