    Hello,

    My Dell inspiron 15 5000 laptop (only 18 months old and bought from Currys) won't start up after I tried to update Windows when this was flagged as being out of date. This appeared to update 100% but then I started getting this issue.

    Most of the time it just shows a black screen with the Dell logo and circle motion as if its about to start up but it never does, just gets stuck at this stage for hours.

    I've tried force shutting it down and restarting by pressing and holding the laptop power button.

    This has resulted in a couple of different screens on occasion but mostly it reverts back to the black screen described above.

    I did follow the Dell Support Assistant system scan prompts (when it appeared on one of my force restarts) to check for any Hardware issues but none were found.

    This then opened up the 'SupportAssit OS Recovery' which detected a failure during start up: 'Error description: OS_BOOT_FAILURE'. I clicked to repair files and no issues were detected.

    I then just restarted.

    Another screen which has appeared both during this latest issue and a few weeks ago is a blue screen saying:
    "Your PC ran into a problem and needs to restart. We're just collecting some error info, and them we'll restart for you.
    For more information about this issue and possible fixes, visit windows.com/stopcode
    If you call a support person, give them this info:
    Stop code: REFERENCE_BY_POINTER"

    I don't want to do a factory reset as I've got important files not backed up.

    Any ideas what this issue is and how to go about fixing it up without losing any files?

    Thanks

    Scott

    Power off, turn on and get on that f11 key - Troubleshoot - Advanced Options - Startup Repair.

    If that's a bust same thing but use System Restore - Username - Password - Select a restore point.

    I've tried F8 but it doesn't do anything.

    I found a way to get to "Windows Recovery" and it displayed a blue screen saying "Your PC/Device needs to be repaired. A required device isn't connected or cannot be repaired. Error code: 0xc000000f".

    Any ideas where I can go from here?

    If I can't get beyond the logo screen, where can I enter these commands?

    Boot from windows 10 install media and run the command prompt, or just keep shutting it off while it's trying to boot until you get the options screen.

    Brand new from Curry's costing £900 18 months ago. Annoyingly think it's only got a 1 year warranty which in hindsight is poor given the cost and apparent quality brand name (Dell).

    I don't know if it came with a Windows disk, do new laptops typically come with one to allow me to try the boot from install media?

    Couldnt see any obvious options to allow this from just shutting off and on either. What will the option likely be called? Thanks

    In all the suggestions above will I still be able to retain all my files and paid for software?

    I bought a downloaded version of MS Office (Home and Student edition for 1 user) from Curry's about 18months ago (cost £120), which I obviously want to keep. Is there something specifically I might need to do to reinstall this?

    Thanks

    I just will try chkdsk and repair system partition, windows partition "chkdsk C: /r /f /x" your drive letters can be different. On dell there is auto update BIOS from WIndows Update, check to see in BIOS if corect mode is set for your Hard Disk, may be is AHCI or RAID.

    The first thing you need to do is to pull out that hard drive, connect it to another pc and copy all of your important data from it first. Then you can go ahead and try other methods of recovery but if something goes terribly south you'll still have your data some place else

    try update if possible first that way you may manage to keep your files also what is the exact inspiron 15 model there are quite a few 5000 ones because heidoc windows iso downloder has dell iso files available. You could also try booting from windows pe to see if you can recover your office serial number.

    the $900 question is; can that disk still be accessed when it is out of the machine..if yes; backup your files. then clean it up. i would recommend formatting.
    if no, say goodbye to your files and replace it, making backups regularly.i would not recommend w10, as operating system. it is totally unreliable.

    To late now but on most laptops first thing you should do is make backup disks or image.
