After 3 months since KB5034441 was released, it still won't install

You have 2 disks in your system.
Disk 0 is the treated one and disk 1 is not formated, has no drive letter and can't be used by Windows!
Or is it an external disk connected by USB?
If it's not external and always connected to the system, convert it to GPT!

It is a internal ssd, indeed. But I've never used it and I don't know if it has been unformatted since when I bought this laptop (I bought it new, not second hand). Do you think I could make a good use of it? I'm not an expert about disk drives, but SSDs are faster than HDDs, right?

run
diskpart
sel disk 1
clean
convert GPT
crate partition primary
format quick fs=ntfs label="Data 2"
assign letter="E"
exit

You can use it for the storage of your ISO for example or for downloads
You are clever enough to find it out

Letter E is currently used for the DVD drive. Should I use another letter or will the DVD drive letter change automatically?

Then take F

On all machines having a DVD, I set the DVD-Letter to (Z:)
Can be done in Diskmanagement

And keep the last sentence of post #217 in your mind

I've tried the command prompt Pentagon has graciously provided but I am having trouble with laptop. Firstly I get that win re is already disabled. I replaced my partition numbers as outlined but could not extend.
Any assistance would be appreciated.
