Far as I am being told by the owner, this unit came with win7 but he upgraded to win8 and now wants to revert back to win7 after he started getting this error message on boot up: "Error: No boot disk has been detected or the disk has failed". So I am attempting to reload win7 now but seems the wireless mouse which came with it is not working, only the wireless KB works. I just tried a wired KB and that works too but not a wired mouse which I need to make the selection to install windows, it's not the USB slots because the KB's work in both slots.

 

I just loaded Knoppix, the mouse works fine in knoppix so I am lost here, any ideas please?

I would run Chkdsk on the drive before I did anything.

I installed W7 on a computer today and the mouse wouldn't work. I pulled the disc out 3 times and reinserted and all of a sudden the mouse worked again. Don't ask me why.

What is the origin of the install disc you are using?

One problem is on the win7 install screen the mouse is not visible so it's not like I am seeing it and it's not moving. How can I run chkdsk on this machine please?

As shown in this link, since the mouse is not working I can't run chkdsk from the win7 dvd:

Did you reinsert the W7 install disc a couple of times to see if the mouse works?

The mouse wasn't visible on my install either at first.

I asked you the origin of the disc you are using?

Try the disc a few more times.

Yes, I had tried the disc a few times since last night, my disc is a bootable disc made from an ISO, the owner will be dropping off the OEM disc for this unit a little while so I will try with that. Meantime I just ran the Disk Health option from Parted Magic Linux disk, shows no errors.

So does this mean that the mouse problem can be related to the disk or OS on the disk I am using?

More chance it's the ISO you are using. Very often they have trouble recognizing the mouse. I always burn ISO's at 4x speed. I would try again and don't touch the mouse at all till it appears and you have to click "next" You may get lucky.

ok thanks, will let you know what happens after I get the OEM disk later today.

Nope, the mouse is not visible with this OEM disk

What I do is pull the Hard Drive out, hook my caddy up to a working computer and run CHKDSK on the Drive that way.

So you're saying this all might be hard drive related?

Who is to say till the Hard Drive is checked.I wouldn't be installing any OS till I was sure it's OK.

Also, next issue I am seeing is every time I start this pc I have to select the boot order all over again, it always reverts back to UEFI, how can I get the boot order to stick?

Did you shut down secure boot and turn on legacy support first?

Damn Uefi and secure boot seem to survive being turned off in bios often times. I just had an HP laptop where I could boot to a cd by using F9 after shutting off Secure Boot and Uefi but it would still boot to them if I failed to hit F9. The F codes seem different in every brand.

Oh sorry, I forgot to post here, when I disabled secure boot and chose legacy, all went well from there.

Great! I'm glad to hear it. :D

Good for you!

Might it be. with the mouse, that the batteries in the mouse are dead. Just a thought bu it has happened to me
