Being
not familiar with the Dell Vostro laptop, or that error code, I'm just going to ask you,,,,
How old is this Laptop? And, what was the original OS? How much ram does it have, and is the hard drive mechanical or SSD?
I wouldn't have any problem at all, installing Windows 8.1/Pro/ 32 or 64. I have both ISO's on Flash Drives.
But maybe some prep work on the little PC, would be best before any OS INSTALL.
How are the batteries? Both Main and CMOS? Main Battery should be in good condition and able to be charged to 100%.
And, the CMOS battery MUST be at 3.0 vdc minimum, or it would need replacing.
I'm looking at this from the standpoint of a Computer Tech, being asked to install an OS to that laptop. I've done that a few times before.
Next, I really have to ask, "Why Windows 8.1?" It was a
great little OS, back in its day, but that day is now long past.
I had 8.1 on every one of my dozen or so, PC's and Laptops, just a few years ago.
But that was then, years ago, and now the best OS for an older PC or Laptop, is some version of Windows 11.
Working with different OS's is my hobby, now that I'm retired.
My latest OS to work with is "Windows MICRO 11" Pro/64. With the MS/BS all removed, it downloads in just a few minutes, burns quickly to a Flash Drive, using Rufus, and then installs in just a few minutes.
I've installed MICRO 11 several times now, to different SSD's on different PC's. It runs really good on an old HP laptop with just 4GB of ram, and a Crucial 120GB SSD.
Drop me a PM if I can help you.
