tablet update

Hi, hope someone can help as MS cannot, I am trying to update my tablet to Windows 1709, I get as far as ready to install, it asks for more storage, it will not recognize my 32GB micro card,whatever format I try. I can get it to use 16GB USB drive up to 75% then it stalls, if I try fixes suggested, I have to restart, which puts me back to start of install. Then it says USB failed previously, and now windows cannot recognize it. I have also tried a 160GB USB drive with same result, I now have no hair and am ready to buy android unless,.... Please help!P.S. Update assistant is also telling me that my PC cannot be updated. ( but does not say why). Thanks.

What make and model of table do you have? There's a page for a 2nd system in your specs, so you could add it alongside your Desktop. https://www.tenforums.com/profile.php?do=extra1

What version of windows do you have on the table at present? Is it 1607? If so, let's get one thing out of the way first. Some PCs (mostly tablets) use processors that are no longer supported for Windows 10 and cannot be upgraded beyond Anniversary Update (1607). For affected PCs (and only for those affected) 1607 will continue to be supported until 2023. For more details and how to check if yours is affected see...

The USB should be formatted as ntfs to be able to use it as extra storage in an upgrade. Was yours?

... I find the only real reason to reformat as NTFS or exFAT is to work with single file sizes greater than 4GB, also a limit.

This usb was being used as extra storage for a windows upgrade - who knows how large the files would be under those conditions?
