Computer extremely slow during and after clean install and reboots.

Good stuff mate keep us updated because I ma sure there has been some "cross infection" on your install and the clean drive will eliminate that rot.

Hi ICIT2LOL,

I couldn't use diskpart because it says clean all is not allowed on the disk containing the current boot etc.
I even tried safe mode with command prompt.
Have you got any other ideas please mate?

Thanks in advance.

EDIT:

I just had a thought.
Is there a system that I can put on a USB and boot from, this way won't I be able to run diskpart from that for the C: drive?
I read a thread where this was said...

whs said:

Maybe SIW2 can find a way to put it on a WinPE stick. He is the expert on that.

...although it was about Bootmgr - Copy to C:\ with EasyBCD in an excellent tutorial by whs.
Is this possible maybe?

EDIT, EDIT:

Is there a way I can use diskpart clean all during the clean install?

Thanks Megahertz07.

I am re-installing and when I got to the partition stage I deleted everything there to leave a single unallocated space of 465 GB (my hard drive is 500 GB).
I then clicked the red cross to cancel the installation and entered system recovery options where I selected the Command Prompt.
You can see from the image below the current status (I know this will take in the region of 2 hours to run).
What is the Disk 1 please and can I run clean all on that too?
I don't understand that because there was only a single unallocated space of 465 GB shown after the deletion of all the partitions>

Thanks in advance.

UPDATE:

DiskPart has succeeded in cleaning the disk.
I noticed that Disk 0 now has an asterix (*) to the left of it.
I assume that this means that particular disk is still selected?
I would just like to know if I need to clean all Disk 1 (and what it is) please?
Pehaps this could be the reason for my problems doing a clean install?

Thanks in advance.

Sorry Paul I should have said you would have to use another machine to clean the drive cos Windows can't clean itself if you get my drift. Anyway looks like things are going in the right direction now.

Now if you go to Computer right click and pick manage then Disk management you should see those drives in there and if disk 0 has been cleaned it will show up as unallocated.
Now I normally leave it like that if I am going to reinstall but some like to format it and partition it ready but Windows will do that as it installs anyway.

A good program for doing this stuff to is Partition Wizard Best Free Partition Manager for Windows | MiniTool Partition Free a very handy tool to keep mate and the interface is just great to work with when run it will show the drives and the status as described. See pic of this machines PW GUI

Not going well .

I have tried reinstalling again after clean all using DiskPart and it is even slower now than before.
It has been sitting on Expanding Windows files (0%) now for over an hour and that is booting from the recovery disk that came with the computer.
I even reset the BIOS back to default.

My brother-in-law is dropping round an 80 GB HDD later so I will try that and see if it works.
If it does, then all well and good and I will know it was the HDD, but if it doesn't then I am afraid that it must be another issue, although I can't think what that could be.

Out of interest, at what stage should I remove the installation disk?

Thanks in advance.

EDIT:
The HDD light is constantly on so I assume that must be doing something!!!

EDIT:
I have restarted from scratch and it is now installing, well at least it is Expanding Windows Files at the moment.
I will remove the installation disk at the first restart.

My brother-in-law is not coming until tomorrow now so if I still have problems then I will try the other HDD tomorrow.

Hmm to save me scouring back through the thread Paul have we done a memtest on the machine??
