Another day.....another learning curve !!......So I lent one of my Toshiba Satellite's to someone, and they have totally messed it up, anyway, I am trying to re-install W10 from a USB drive.....I keep getting the message "Windows cannot be installed to this disk. The selected disk is of the GPT partition type".........any help appreciated.....
O.K Thanks.....done that, it now says "EFI partition is formatted as NTFE....format system partition as FAT32........How do I do this ?..........
Clean Install Windows 10
As part of the procedure (as I think I said in a previous recent thread of yours) you DELETE all partitions on the existing drive and install Win 10 to unallocated space.
You do NOT install to existing partitions on the drive.
See around steps 13-15 of that tutorial.
---------------------------------------------------
Now if you had made sure you had a current 3rd party program disk image (a compressed copy of the used parts of all partitions on your PCs disk) saved to a drive you kept at home, you could have restored that and been back to exactly where you were- without the need to struggle with a clean install, and saved a lot of time....I lent one of my Toshiba Satellite's to someone, and they have totally messed it up
The routine and regular use of disk imaging is endlessly recommended here.
Windows can be installed in two ways: Legacy-MBR or UEFI-GPT
To install as Legacy-MBR you must boot the installation drive as Legacy
To install as UEFI-GPT you must boot the installation drive as UEFI.
As you have a UEFI BIOS, you should install as UEFI-GPT
Detach any other drives from the MB.
During POST, press F12(?) to launch the boot menu. You will see two options for the USB drive. USB UEFI (Name) and USB (Name). Select USB UEFI (Name) if you want to install as UEFI-GPT or select USB (name) if you want to install as Legacy-MBR.
Go to install and delete ALL partitions on the main drive till you have one and only one unallocated space and then proceed.
If you don't want to use MS account, don't enable updates or connect to the internet during installation.
Well, I managed to sort the problem, by downloading W10 from an identical machine, of similar age to this one, and onto a DIFFERENT usb drive......all up and running now !!......thanks once again for the replies.......another learning curve !!
Just one final thing......it seems a bit weird really.......on the machine that I downloaded the second USB drive from, it says that W10 was installed in 2022.......on the "problem" machine, which is now working fine, it says that W10 was installed in 2019......how can that be ??.......
Del,
If you want others to comment, you'll have to state how you retrieved the dates on those two computers.
Some of the attempts I've seen to retrieve original installation dates have had shortcomings.
I use this PS script and it seems to give correct answers.
Taken from Find Windows 10 Original Install Date [Option 4] - TenForumsTutorialsCode:$UserDesktop = (Get-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" -Name "Desktop").Desktop Get-ChildItem -Path HKLM:\System\Setup\Source* | ForEach-Object {Get-ItemProperty -Path Registry::$_} | Select-Object ProductName, ReleaseID, CurrentBuild, @{n="Install Date"; e={([DateTime]'1/1/1970').AddSeconds($_.InstallDate)}} | Sort-Object "Install Date" | Export-CSV -Path "$UserDesktop\InstallDateList.csv"
- I just added a bit to it to include creating an output file in csv format on the user's Desktop.
- It only reports up to & including Version 1909. I had not noticed that before. I've just posted about this in the tutorial thread.
All the best,
Denis
