A required drive partition is missing / inaccessible boot device?? Inspiron 7520
I have a DELL Inspiron 7520(service tag 4fb1gs1). Originaly supplied with win7(sp1) home premium 64bit, Intel core i7-3612 QM @ 2.10 ghz, 8gb ram. I can't pull up any other specs due to my current laptops lack of operation.
The issues--
I decided to take advantage of the win10 upgrade. Microsofts tool checked and approved my device for the upgrade. The initial upgrade worked and my laptop was now win10 home. After a check to see if my Win10 has been correctly key activated, I decided to do a pc reset (clear files, apps and settings) via MS tool in settings. After finishing reset and rebooting to desktop I get the error "inaccessible boot device" and than proceeds to go in a loop of restarts.
Figured I would try now a clean install via USB boot using the MS creation tool. Using the repair and fresh install options and after completing some intial start settings I get the error "unable to reset your pc. A required drive partition is missing"
So I am now officially stuck with no pc. I searched for hours online for an answer to this problem to no avail. Even this message was done frustratingly through a cell phone.
I am the family resident service tech and I assumed I was tech savy. Before I swallow my pride and goto geeksquad......
Is my laptop bricked?
Anyone know of a solution?
I will be checking my cell phone for any replies......

Well low and behold, I decided to give the install one more chance and it worked. I really have no clue as to why that happened. But I am up and running.
Thank you for the assist!

Start with a hard drive diagnostic - F12 at powerup. Choose Dell diagnostics, and run an extended test on the hard drive.

I am currently using Dell ePSA preboot system assessment. Build 4220.10 UEFI ROM.
All devices passed intial test.
After looking at the configuration tag I have - drive 0 - ata, sata 1tb. And - drive 1 SSD 32gb. Also it showed boot path-MBR of drive 0. File system-NTFS.
I am now running a thorough test and seem to be stuck or lagging at 10% on drive 0 for 40 min. Its not frozen I believe due to thermostats temp keeps changing in system health tab.
Not sure if I should abort and start over?

See what happens, but it sounds like your cache drive is OK, but your hard drive has developed bad sectors - meaning it needs to be replaced.

Thorough/long test has completed....all devices have passed test.
Any ideas on where to go next?
If this a partition issue, cant they all be wiped and start fresh?
