E7390 SSD in WWAN port

Not the one you suggested for 2 reasons. It is a SATA drive you linked to and that is a PCIe slot and that is a 2230 slot not a 2242.

From the owner's manual.

Thank you!

So definitelly a PCIe NVMe hard drive.

Regarding the form factor - seller of my laptop send me email that I should buy M.2 2242 form factor drive, not 2230.

OK, after further checking it appears that some retailers such as Crucial only supply SATA drives yet others such as Mrmemory state that PCIe drives are compatible. Are you confused yet...I know I am. The following posts should help. And since you have contact with the previous owner, what do they suggest as they obviously had a drive in there that was working.

And this from the tech specs

I have bought the laptop from a reseller selling regualry hundreds of refurbished dell laptops (waiting for the NBD warranty transfer to my company - then I will be able to ask Dell Support for details).

This company wrote to me that in the WWAN/SSD port I can mount  PCIe NVMe M.2 2242 SSD hard drive (without any specific example model, although ie. Toshiba RC100 fits these requirements.

Hey - I’m a little late getting in on this - sorry.  Where would I get the bracket to mount the SSD in the WAN port? Do you have a part #?

Thanks so much!

Welcome to the Dell Community  @MWA_JeffW 

He installed an M.2 2230  30mm

If you install an M.2 2242 42mm you should not need a bracket.

Can you check your size just to make sure???

Best regards,

U2

Thank you!  Is this going to work?

@MWA_JeffW 

Does the BIOS see it???

Does Windows see it when you try to install the OS???

Ok - I have the drive and I installed it.  I get "no bootable devices" at power up.  What am I missing?

Toshiba OCZRC100

M.2 2242 PCIe NVMe SSD

Any help, please.

@MWA_JeffW 

What OS have you installed on the drive???

Regards,

U2

Thanks for the response.  There is no OS.  I installed the drive in my laptop so I could install the OS.  On boot it shows no bootable devices.  The laptop does not  recognize the drive in the WAN port.

I updated the BIOS to the newest version - 1.9.3.  My situation has not improved.  The system does not recognize that anything is in the WWAN slot.  Is there something I need to turn on in the BIOS or??   I'm at a standstill.

Thanks, by the way, for the help so far.

@MWA_JeffW as previous posters in the thread have suggested, the slot will only accept the 2230 style drive with an additional bracket. The drive you have purchased, the 2242, doesn't work with that slot hence why it is not being detected.

As per JOceans post
