Windows 10: After changing motherboards I used my old hard drive/SSD to boot.

I got a new motherboard and cpu. The installation went great and I went to boot it and the motherboards bios did not recognize the drive until I changed it to legacy mode. Once the system went into boot it stalled at 25% getting devices ready after three hours I unplugged the internet and keyboard and restarted only to have it stall at %11. Not what to do next.

Boot from old hard drive

The motherboard of my old computer died suddenly and so I bought a new computer. It has two 1TB HDDs on RAID 0 and comes preinstalled with Windows 10 Home. I wanted my computer to boot from my old 120GB SSD from my old computer but it doesn't seem to recognize it as boot drive. It was working perfectly with my old computer.

I can view files from the SSD and so this confirms that it is working. The boot partition is marked active.

I tried changing the boot hard drive in the bios but in the bios, the only two options shown in the boot menu are

• Windows Boot Manager (Intel Volume1)
  
• CD/DVDRW
  

After searching online, a website suggested swapping the Sata of the old hard drive with that of the new one. I tried even this but this didn't work either. It gave me the error "boot disk not found" and in the boot menu, the only option was "CD/DVDRW".

For Reference :

Motherboard : ASUS Z170 PRO GAMING

All Hard Drives Run GPT.

Any other solutions?

 

new ssd, installed win 10, first in boot order but still boots from old hard drive.

I have a pc with a standard hard drive running windows 10 just fine. I got a new SSD. I unplugged all the hard drives, installed the SSD and installed windows 10 on it. I would boot just fine. I then plugged the old hard drive back in thinking I
could switch between these boot drives using the bios boot order. I was able to switch back to booting from the hard drive but now when I change the boot order to the ssd first it always skips over it and boots the from the second option which is the old
hard drive. I thought hard drive data was just data and the bios could choose which drive to boot from but it doesn't. I can see that the old hard drive is listed as active in disk management. It seems like windows will mark only one hard drive as active
and the bios must boot from that no matter what the boot order is. Is that how it works? Is there a way to switch between booting from either drive without opening up the pc and unplugging the other drive each time?

 

Gigabyte motherboard, pc won't bootup after recent hard drive change

So I've previously had this problem when I added new SATA hard drives to an old one, all I had to do was switch hard disk priority to the one I wanted to boot from. But that's not working right now.

Error message: AMD Data Change...Update New Data to DMI!
Specs:

• Motherboard: Gigabyte ma785gmt-ud2h
• Four SATA hard drives, three 2tb and one 1tb
• One IDE hard drive, 160gb
• 6gb RAM
• Everything else is the default

What happened: I had an Amahi home server running on this PC with Ubuntu 12.04LTS as the OS. It was using the four SATA hard drives and everything was running smoothly. Then I read that it's easiest to have a setup where the OS/Amahi is installed on one small hard drive while the large hard drives are used to keep the files on, this makes it easy to update the OS without worrying about the files. So today I installed Ubuntu 12.04LTS on an old IDE 160gb hard drive that I had laying around, which would be perfect to use since there is exactly one IDE port on the motherboard.

I disconnected all hard drives, connected the IDE, installed Ubuntu, and rebooted. I got a "AMD Data Change...Update New Data to DMI!" message.

What I tried:

• Have the IDE be given priority over other hard drives.
• Connecting all the hard drives back, with and without the IDE hard drive. Same message.
• Disconnect all hard drives, connect IDE, and set BIO to opimised defaults. Same message.
• Disconnect CD drive with only IDE attached, same message. Reconnect CD drive, same message.
• Disconnect CD drive with only SATA attached, same message. Reconnect CD drive, same message.
• Disconnect CD drive with SATA and IDE attached, same message. Reconnect CD drive, same message.
• Just IDE connected, mess with the peripheral settings by changing "OnChip SATA Type" to ATHCI, RAID, or IDE. Tried this with "As SATA Type" and with "IDE" set for the port4/5 type
• Just IDE connected, disable SATA controller
• Disconnect IDE, reconnect original hard drives. I still get the same DMI message.
• Attempt to boot from the SATA hard drive that has Ubuntu on it, using each of the SATA ports.
• Update BIOS to F10B, disabling the "Remember DMI" option. I reconnected all hard drives and the CD drive (the pdf said the 'system' will redetect all devices). Now I got the "AMD Data Change...Update New Data to DMI! Update Success" message, still hanging there. Rebooted, now it's the original message.

So I am at a loss. Any suggestions?

Edit: there were many suggestions to try clear the CMOS, however that didn't seem to help the posters. I haven't tried that, but if people suggest I should then I will do so tomorrow.
