Hey guys

New build running Win10 - installed over the weekend.

I have an 500gb SSD running Win10, a blank 2TB 7200 HDD, and my old 1tb from my old PC (the 1tb had my old copy of Win10 on it)

When I boot from either a shutdown or a restart, I get the BIOS splash screen and then straight away "No boot drive detected". If I go into the BIOS to begin with, exit without saving, it loads the SSD correctly and I can get into the OS.

The SSD is the #1 priority boot, and it is plugged into SATA 1 on the MOBO.

I've tried resetting Windows - no joy. MOBO is fully up to date.

I'm stuck on this :-( Spent most of yesterday trying to figure it out. .

Any help would be greatly appreciated.

Link below is my Disk Management screen - one thing that occurred to me was the my 1tb might be doing something? Windows is split between the two drives or something? Error still occurs if the 1TB is not plugged in tho

As you can see in Disk Management picture - bootloader partition is located on 1TB hard drive.
So for boot process to work, 1TB hard drive must be set 1st in BIOS boot order.

You get such configuration when more than one drive is attaached during windows install.

If you want to boot from SSD, easiest way to resolve is to disconnect all HDDs; clean SSD and reinstall windows.

There are certain ways to resolve this without reinstall, but it requires some advanced activities like copying, moving partitions and bootloader repairing.

Welcome to the community, SivadYar!

You are most probably confusing the system while having two Windows 10 installation on two separate drives. Since the 1 TB HDD containing the other Win 10 OS is from your old PC, you won't be able to boot from it properly on your new rig. The OS is tied to the motherboard where it was originally installed on that's why you'd need a new genuine Windows 10 installation for the new motherboard.

If you want to use that old HDD as a secondary storage drive on your PC build, then you should definitely consider backing up all the important data from it somewhere else. Afterwards, you should reformat the drive through Disk Management. Getting rid of the system partition might help you boot properly from the SSD.

Good luck!

Hi Soph - and thankyou for the welcome :)

I have already formatted the Primary Partition of the 1TB, but I am unable to get rid of the System Reserved or Recovery Partition (keeps saying its needed - guess that's a clue :p). Is there a way I can wipe the drive completely, including the System Reserved Partitions?

All personal data, folders & files are already backed up. I can flash these drives without worry :)

Cheers

Ok so this looks like a plan :) I remove the 1tb & 2tb HDDs. Then re-install Win10 onto the SSD. Should I wipe the SSD first? How do I do that whilst using it?

How can I wipe the partitions and windows 10 whilst using the drives?

Hey there again, SivadYar!

@SkyNetRising is right! It seems like you have encountered an OS confusion while installing Windows 10 on the SSD. This usually happens when you have more than 1 SATA drive connected to the motherboard.
Now that you have unplugged the secondary HDDs, you should be able to install Windows 10 on the SSD without formatting it. The Windows install will wipe the drive for you.
Once you have Windows up and running on the SSD, plug back the secondary drives and attempt to reformat the system partition on the 1 TB HDD. I believe this time you shouldn't encounter any issues in the process.

Keep us posted, though. :)

You boot from win10 install media;
Choose Repair/Advanced Options/Command prompt;
use diskpart utility to clean your SSD.
Commands will be like:
diskpart
list disk (this gives list of attached drives, your SSD should be number 0)
select disk 0
clean
exit
Click to expand...

Note - clean command does exactly that - cleans everything from selected drive. Be very carefull with that.
Don't clean the wrong drive. But that should be no problem if only SSD is attached.

Cheers guys - removed the HDD's and re-installed Win10 onto the SSD. Made sure to delete all the partitions and reformatted the SSD during install so it was completely fresh and now it works a treat. HDD's have been wiped also.

Thanks again :)
