My friend has recently been having problems with his computer where it will just boot up and show a flashing dash symbol. We tested one of my harddrives on it and it booted just fine. We wiped his harddrive and reinstalled windows using my computer then tried booting his computer with the fresh install of windows yet it still didnt work. we went in to the bios and we found that it could detect the hdd but it couldn't detect it with the windows boot software. Any solutions?

Here is the solution to your friends problem.

First of all go into the bios settings of the motherboard, if the board is relatively new then it should be Uefi capable.

If so, first check to see if there is an option in the bios menu pages to select the advanced bios options Oranod.

Once selected find the menu page that deals with Sata ports and make sure the mode is set to Ahci mode.

Next you need to look for the option CSM mode.
Make sure it is enabled in the bios.

Bellow it is an option setting for the type of boo table hard disks or SSD drives the bios can detect.
Older drives have Legacy based bios firmware, And new drives can still use Legacy based bios firmware, or be Uefi based for detection and booting of the drives.

Set...
You can't expect this to work. When you install windows, it is using the drivers for the hardware on your computer. Now you want to take this out and install on new computer with different hardware ?????

When booting, it's now looking for drivers for HIS hardware which it can't find and at the same time it trying to load drivers for YOUR hardware that it can't find.

In addition, depending on OS, if the OS was activated on your Hardware, it may never activate on his hardware because the OS is now tied to your machine.
's trying to find

I was able to use another harddrive with windows on it from my PC and it booted correctly without a problem

That is very much of a *sometimes* thing.
It does not work all the time.

Anyone that tells it does work "all the time", simply hasn't done it enough to see it fail.

Older drives have Legacy based bios firmware, And new drives can still use Legacy based bios firmware, or be Uefi based for detection and booting of the drives.

Set the option to Legacy op rom / Uefi. to detect both types of devices depending on the bios firmware they use.

As long as you do not have two drives that are connected to any of the Sata ports of the motherboard.
That share the same drive Letter Assignment such as C:

You must remove the other drive while doing this that is, or in most cases the C: drive or the default drive letter assignment windows chooses by default to install a windows os.


Then the new ssd drive should be seen in windows install and setup, showing in the box where you choose what drive you wish to install windows on Oranod

Make sure all of the steps in order are done with the drive connected to your friends system.
So windows can get the correct core driver set for the motherboard and chip set his board has.
