    Hello everyone,

    I have an acer v3 laptop and since a few days i'm having a problem with it. It started to have a reboot loop giving me a blue screen . I can't even get into the windows start up,nothing. So i couldn't access the recovery from the inside .
    So i went ahead and i started googling. I couldn't acces the recovery,nothing, ALT +F10 didnt work as well.
    Untill one day when i went into BIOS and i changed it to "Legacy Bios", thats when i could actually access F12 and boot into the usb where i put anoter windows os on it with the hopes of either reinstalling it or accessing the repair instead to be able to just do a recovery or factory resetting. And it did work!
    When i went to reset or recovery it said the drives are locked and i couldn't do that. So i tried the other way and i tried to reinstall the windows...that didn't work either. All the partitions were GPT and and they it said all of them are microsoft partition so i couldn't install anything on it.
    I went to the command prompt (when u choose repair pc instead of install windows) and i tried the disk part ,list disk like it said in google,see all the partitions and indeed, there are only the recovery,new push button factory reset etc... i delete the volume 1 where no recovery or anything was on,just the 400+ gb hdd and then i went back to the windows instalation to create new partition out of that and install there,but still it didnt work...
    I tried to "convert from gpt to mbr" thru command prompt without deleting all the volumes.
    I have seen a version where u clean delete everything on the disk in command prompt and then try convert to MBR but i am not sure if i should do that because i wouldn't want to loose my factory resets and windows that its automatically installed in the laptop and its legit.

    is there any other way of doing it so i can finally either reset or install windows? Or is its going to affect my factory data and recovery on the partitions if i delete it all to see if then works to convert it to mbr? I can't do nothing with that laptop right now,im stuck on it and i need to make it work. Going into windows doesn't work at all as im stuck in reboot loop. Thank you!!

    CjayB,

    You need to change Legacy BIOS to Secure Boot UEFI BIOS for the Recovery Image to work. So do that and boot from your Windows DVD. Open a Command Prompt and start diskpart.

    Type these commands...

    list disk
    select disk 0
    list par

    Can you let us know everything revealed by list par?

    If i change to Secure boot UEFI Bios my usb won't even boot. Because the hotkeys don't work. I've tried that and nothing happens it just goes in a reboot loop . This is why i went to Legacy Bios where i could actually go to "repair pc" from the intallation of windows on the USB i mounted.

    OK, try from Legacy.

    Do you have a Win8 DVD?

    No i don't. The windows 8 came preinstalled inside the laptop and i only put some random windows 8 on an USB to see if i can boot. I tried the UEFI though now, and it said "diagnosing pc" "autoatic repair" . Then it said "automatic repair couldn't repair your PC" . Log file:\System32\Logfiles\Srt\SrtTrail.txt. then it gave me the Advanced option , options. I went there and i went to CMD .
    I typed DISK PART

    -list disk -
    It says : DISK 0 - Status Online - Size 465 G - Free 0 B - Dyn - Gpt with a * which means its Gpt

    -select disk 0

    - list part

    - pARTITION 1 - Recovery - 400 mb -
    -partition 2- system - 300 mb
    Partition 3 - reserved - 128 mb
    Partition 4- primary - 443 GB
    Partition 5- recovery - 350 mb
    Partition 6 - recovery 21 gb

    Those partitions are consistent with Win8.1. None missing.

    Somehow you need to restore your Recovery image in UEFI. Is the laptop under warranty?

    Not anymore. No.

    I tried again "reset your pc" . It said. Unable to reset your PC. A required drive partition is missing.
    I tried "Refresh your pc" and it said, the drive where windows is installed is locked. unlock the drive and try again.

    Your Windows won't load in Legacy/MBR.

    We don't know why your computer was getting those BSOD. Maybe a hardware problem rather than software. I'd contact Acer for advice.
