GPT Invalid on USB created from iso

[kevinH]

Hi, I am returning to Armbian after quite a few years. I was trying to follow guidance from nexbox-a95x-armbian and after a search found the debian &  Ubunt images (https://www.armbian.com/uefi-arm64/) which I downloaded and wrote to a USB using Rufus (also balenaEtcher). I then tries to look at the FAT32 partition contents but the GPT was corrupt - tried many windows tools and Linux.I "repaired" the GPT using Linux tools but then the FAT32 filesystem was corrupt.

 

What am I doing wrong?

 

any help much appreciated

If I remember correctly, recently there was a similar thread on the forum re GPT corruption under windows. Not sure, but there might be some useful info.

Alternatively, flashing under Linux might be an option.

There are various recent reports of windows corrupting the partition table.

Well using Linux to write the USB appears to have fixed the problems. 

Damn Windows

 

Thank you for the pointers, much appreciated.

Although writing the USB using Linux produced a good GPT the efi partition (FAT32) is unmountable and hence I cannot change anything. I tried gparted to fix it but the checkdisk failed. Hence I cannot follow the original guidance I had found. 

 

Where am I going wrong?

 

thank again for any help

Flashing under Linux  you will have many options to do it and check some problems on partitions etc. Normally, I use the Balena Etcher and dd by console.
