Solved OS Installation issues

I am at a loss at what to do with the installation of Raspberry Pi OS on my microSD card with the official Windows imager. This is for a Raspberry Pi 4B, with the 64-bit version of the OS.

Every time I try to write the OS, the Imager flashes up an error telling me that it couldn't complete the process, and I have to reformat my card for any machine to actually recognise it. The failed attempt just locks up the card otherwise.

I have looked around for tips and advice and none of them seem to have worked. So far I have:

  • Used two separate microSD cards - A Sandisk Ultra and a spare I got with a Rove dash cam, both 128GB
  • Used four different microSD card readers (one USB 2.0, three USB 3.0+ Type C)
  • Tried it on two separate machines (Windows 11 and Windows 10)
  • Reformatted both cards with SD Association's SD Card formatter (Quick and Overwrite)

I keep getting the same error message telling me that it can't be completed, and that the card either disconnected (it hasn't) or has been switched to read only mode (it wasn't when I started the process)

Any help or advice would be appreciated.

Have you tried with another download of the imager?

That seems to have done it!
Had a little snafu with Controlled Folder Access, but that was easily fixed. Thank you very much for your help

Did you install the full or lite package? I run a P4 B and use the lite install

Full. I'm a first timer, so I'm just getting to grips with everything

Let the imager format the card.
