Access denied to C: drive serious issues

The answer to all your question is YES.
So make sure that you have all your important data backep up to an external drive before doing a clean install.
Goog luck.

Good morning All,
Thank you for your patience & help, this is just a brief update on the problems of yesterday. My laptop did not download the ISO file at all, it seemed to be hung up during the set up. It took me another hour to clear the laptop and shutdown!
I cleared the laptop this morning and started again with the Media Creation Tool and this time it worked OK. It took about 90 mins and now I have the ISO on a USB.

I am now ready to reinstall Windows 10 into my PC. There still a couple of questions outstanding:
1. Will this action of reinstalling W10 completely clear everything from my C: & D: drives?
2. If everything is cleared can I re-partition my hard drive so that I have more room in C: and less in D: ? Or even not have a partition at all?

I have just noted the time of my posts and realise that my laptop was showing the wrong time. It is now 12:05 Tuesday 14th June.

Afternoon Jeff,
So glad you got that USB version downloaded! As Badrobot says, the answer is Yes to all your questions.

So, back to my question:
Here is information on backing up/exporting your WLM info.
How do I import and export email, contacts, and calendars with Windows Live Mail? - Windows Help

-Can you do the data export from WLM to an external drive, for importing later?

When you are ready, boot the desktop to the USB, and select custom installation. Then delete all your existing partitions. You want to install to an unallocated drive.



See the tutorial here for more information:

If you have any questions, please ask. Someone will be able to answer you here.
Good luck! :)

Now I seemed to have changed the size of partition 3 (to 901GB) at the expense of 4 but Still cannot install windows because it says that the selected disc has an MBR partition table. It says that on EFI systems Windows can only be installed to GPT disks.

What's all this about? What do I do now?


Now my PC is totally not working, either to load new W10 installation nor go back to the damaged W10 operation.

Might give up altogether with all time I have wasted.

At that point, you have to delete all the partitions and create new.

After deleting all the partitions (I hope you had your important files backed up), select the "Unallocated Space" and click "New" and just follow the prompts.
