Hello Alrose,

                                 I have the same laptop model and OS. Same thing happened to me but after the 3rd attempt, system reverted back to 8.1 (meaning that Win10 was partially installed).

May I ask what BIOS version you're running? Some posters indicated installing the latest BIOS driver  (7737A13.exe)  solved their Win10 migration issues.

My laptop is running on BIOS version A4 and it's been impossible for me to upgrade to a more recent version. BIOS FLASH keeps failing from both Windows and DOS environment.

It's a bummer ...

well at least, my laptop is still working. Read a post from a user who bricked his 7737 after a failed BIOS flash  ...  :emotion-42:

Not sure where to find the bios version , and what happened to the other guy makes me nervous about updating it.

I wish dell would have some information, it is their product i am sure they know whats going on and all the failed installation on  their machines.

People say all kinds of things, some i would never attempt in case i bugger it up.

Dell needs to be upfront and come out with some information, i know it is a windows program we are trying to install and it is not their product, but the problem is actually their machine that will not install it .

so unless it is a fault in the win 10 program then dell needs to step up and help users

This is silly, not being able to install win 10., all they are doing is frustrating thousands of people who can't put win 10 on their machine, i am at the point of just giving up.

Next machine will have it on it but whether i buy another dell i questionable right now

This sours me about wanting to buy dell again.

They should be on these forums helping us

I totally hear you. That upgrade to win10 is turning into a nightmare. Sometimes it feels like I need a Ph.d in advanced computing just to deal with all the bugs and issues that pop up every now and then.

But even after attempting the upgrade from a clean factory reset with full updates and no additional 3rd party software (so as to reduce risk of interference and conflicts), it still doesn't work.

I'm pinning my hopes on Dell's next BIOS version release. Hopefully, they'll work out the issues with their drivers upgradability otherwise I might be stuck with win8.1 on this laptop and I'll have to buy a new one with Win10 oem. Just great, more money out the window :emotion-60: 

But you might be luckier than I and already be running the most recent version. The way I check my BIOS is either via : control panel /system and security / administrative tools/ system information (it's the 11th line from the top -> BIOS Version Date)

or click on DELL SupportAssist / System Info / Motherboard (it's the 4th line from the top).

or just use command prompt and type: 

systeminfo | findstr /I /c:bios

And in case you haven't already done it, make a yourself a bootable rescue DVD or USB & backup your system. This might literally save your device from becoming unusable in case of a major issue!

Stay safe :emotion-35:

Hi Bluemoon

the BIOS  version/date is   Dell inc .A05,  2013-10-31 

Looks old maybe it needs an update

Actually i have given up on win 10. i'll just keep using 8.1 ,i am used to it, win 8.0 was a nightmare but i don't mind 8.1

Thanks for the advise, much appreciated

I had this problem but it was solved by updating the Bios to A13 version.  No problems in flashing the new bios, very straightforward.  Create recovery methods just in case, Macrium Reflect is a very good free programme.  Best of luck with Windows 10, it is a bit of an anti-climax once installed, not much different to Windows 8.1 and the 7737 STILL has a lousy keyboard!

yeah alrose might be on to something. Think I'll follow his cue and wait for the waters to settle and Win10 to be more road-tested. Not actually talking about smashing laptops on the highway lol

Jh, thx for the insight. How in the Freakin Bell were you ever able to flash your BIOS. I've been trying every single method on the net for two weeks with no success. Currently running A4.

Did you just upgrade from Windows with Antivirus off? :emotion-42:

The 7537 and 7737 both need to be updated to A13 for a successful Windows 10 upgrade.

So Philip,

                       I proceeded to  update my BIOS to A13 from a DOS environment using a USB bootable. Due to the new windows 8,1 EFI parameters, I needed to: 

- disable secure boot

- enable legacy

                                            AND  

switch BOOT system to LEGACY from UEFI

after restart, laptop did boot into the legacy interface and I was able to successfully flash my BIOS.

The problem now is that the laptop only starts in LEGACY and since Win 8,1 only works in EFI, I can't access Windows anymore. 

Is there a way to get back to the prestart panel and change the boot mode back to UEFI.

thx!
