An invaluable article. I don't know much about computers on this level, but stumbled into this article, and it let me recover my Inspiron 11-3000 with the soldered in 32GB Sandisk DF-4092. I had tried the factory OS reinstall using "Dell OS Recovery", but it just ran for a half hour and gave a useless error message. I'd also tried installing from a MS copy of Windows 10, 8.1, & 7., but it said disk control not set correctly. Since I've never successfully tinkered in the Bio setup, other than changing boot order, that was not where I could go.
When I called Dell, they told me the warranty only covered hardware, but they sent the job number and transferred me to Software (on the other side of the world). The Guru there told me that my machine was an "experiment", and Dell didn't realize that Windows 10 would grow and updating would fill the disk. He kindly offered to sell me a new machine with a magnificant $50 discount, for only $299. He didn't have a solution, and didn't want to talk about a possible retrofit of a larger SSD that would fit and work. Since it won't boot, and is too small for a boat anchor, I decided to let it all hang out, and try the above dos commands. The difficulty then was getting a dos command. I'd already exhausted my abilities with Hiren's boot disk 15.2, but downloaded a copy of 16.2, and after I gave up waiting for it to boot, went off to other activities, only to come back to a windows screen with a dos prompt icon. The above solution worked like a charm. Then I tried installing Windows 8.1, and it found the disk, with 28 gb free, but no partition. I then ran my Dell factory recovery, choosing to wipe the disk, which said it would establish the partitions. It did, I'm back to a fresh machine. I turned off wireless till I could disable Windows10 update, reinstalled Chrome, Winamp, and VLC. Now I'll get my .epub reader, a memory card for music storage, and have a good entertainment machine (with headset). Thanks again for the DOS commands.
Probably a little late, but look at my reply to Gallant Fox post. (Unless you bought a smaller boar). I download the Hiren's from their web page, but it still was numbered 15.2 on the file, so I labored thru one of the other downloads, being careful not to take the other forks. It took forever for 16.2 to boot, and if I'd not have other things to do, I would probably have given up. You can burn a USB with the Dell OS Recovery Software, and reinstall after converting to the GPT. I suspect the Bios won't work with any other version or copy of Windows, but didn't pursue that avenue.
Mine was a brick, pretty much out of the box. Thanks for posting this! All I wanted was a light-weight machine for blogging and writing, which I finally have!
BTW - If you're stuck on the how to get the cmd, it's Shift + F10 before the language options screen.
