Installed SSD, computer refuses to boot to it.

[spcespff]

I installed a SanDisk SSD to my older HP desktop running Windows 7. Install went clean and I cloned my HDD to the SSD. I opened BIOS and tried to make the SSD the boot drive. Old HDD is plugged in to SATA3 and SSD is plugged in to SATA5. When I boot with the SSD I get the error BOOT FAILURE. REBOOT AND SELECT PROPER BOOT DEVICE OR INSERT BOOT MEDIA.

I have tried unplugging the HDD SATA data cord to no avail. Computer boots just fine when HDD is selected. BIOS won't let me have both drives boot; I have to chose one or the other.

Thanks for reading and thanks in advance for any help!

not clear what BIOS type are, usually all UEFI/EFI BIOS support SATA SSD type as boot drive, consult HP for better info. You can't have cloned windows side to side so move your saved files to SSD and make your SSD as boot drive

Something went wrong with your clone process.
Likely you neglected to clone over the boot partition.

Assuming the system still runs OK with the original drive, redo your clone.

Just like this:
Specific steps for a successful clone operation:
-----------------------------
Verify the actual used space on the current drive is significantly below the size of the new SSD
Download and install Macrium Reflect (or Samsung Data Migration, if a Samsung SSD)
Power off
Disconnect ALL drives except the current C and the new SSD
Power up
Run the Macrium Reflect (or Samsung Data Migration)
Select ALL the partitions on the existing C drive
Click the 'Clone' button
Wait until it is done
When it finishes, power off
Disconnect ALL drives except for the new SSD
This is to allow the system to try to boot from ONLY the SSD
Swap the SATA cables around so that the new drive is connected to the same SATA port as the old drive
Power up, and verify the BIOS boot order
If good, continue the power up

It should boot from the new drive, just like the old drive.
Maybe reboot a time or two, just to make sure.

If it works, and it should, all is good.

Later, reconnect the old drive and wipe as necessary.
Delete the 450MB Recovery Partition, here:
