Setup Installation :: Acer Aspire V5 - No Operating System Found After Windows 8.1 Upgrade
Aug 11, 2014
Acer Aspire V5 laptop that was running an OEM Windows 8 to upgrade to 8.1.
After selecting the Upgrade to Windows 8.1 via the store, the system went through it's install procedure, however after it does an auto reboot, it gives you a blank screen with the message No Operating System found, in the upper left corner.
But, you can turn the machine off and back on, and it will boot just fine. However if you select restart it does the same thing "no operating system found", on restart and again you must power down and power back on.
I have searched for fixes, but all seem to point to some sort of re-install process. I am not to crazy about the idea of re-installing to factory settings or doing a repair back to Windows 8 and attempting to upgrade again, are their any known shorter fixes for this?
And if I do go back to Windows 8, and try to upgrade again, what is to say it won't happen again?

I reinstalled windows 8.1 on my Samsung NP530U3C-A10EE. And now the problem this that I can't boot it without usb stick that contains windows installation files. I can boot up windows and remove the usb stick evertything is working perfectly, but if I try to boot up win without usb, it gives error "Operating system not found. Press CTRL+ALT+DEL to restart". VOLUME C: is one where windows are installed (SSD), System Reserved is the system partition that windows create automaticaly (SSD), volumes D: and F: are my hdd volumes D: is empty & F: is stored with my personal files (photos, music etc.)

I have a Dell XPS 420 and I've just bought an SSD for it. Every time I boot the machine I see "Operating system wasn't found" now, despite having booted into Windows successfully just before.
The only change I made was connecting a standard SATA 2TB drive - which it boots into fine - but now when I have removed the 2TB drive I cannot boot onto the SSD.

I wanted to install w7 so i accidentally formatted some drives. then noticed i cant install w7 because of the gtp partition. as you can see in the pic partition 1 the recovery one looks like it wasn't formatted( i cant remember as i formatted the partitions 3 months ago) so is there any way i can use that recovery partition to restore windows 8
I have tried the alt+F10 menu. none of the following ways in the menu let me restore or reset the laptop. i tried all of the options in the picture none worked
So I am left with an laptop with no os how can i restore the pre installed Windows 8 or install w7 (i have a w7 cd)
The laptop is an aspire e1-571

I bought an Acer Aspire V3-571G brand new a few weeks ago and I'm sending it back for a refund. I'm currently having problems with formatting it. I need to remove all my personal information from the laptop but Windows 8 was pre-installed with no recovery disks in the box. When I try to format the main drive it says I can't because thats where Windows 8 is installed and running from. This is my view from Disk Management:

I have an Acer Aspire M7710 which I installed Windows 8 on.
I wanted to use the reset windows option under the advanced settings option. After selecting the reset option it said it would reboot. This was about 5 hours ago and all I have had is a black screen.
Eventually I powered off my computer after 4 hours waiting as something seemed wrong. When I powered my PC back on I get nothing, just a black screen again.
I thought I would just boot from the Windows 8 dvd and reinstall but for some reason I can't boot from dvd anymore.
I googled around looking for option how I could enter my bios or change the boot order for cd/dvd but I can't get any keyboard shortcuts to let me boot from dvd or enter the bios.
How I can boot from dvd and reinstall?

I am using Windows 8.1. I have an Acer Aspire V5-571P computer with Windows 8.1 pre-installed. I want to install my licensed copy of Windows 7 Professional on it as a dual boot to dual boot Windows 7 and Windows 8.1. I have seen that it can be done, but I cannot figure out how to correctly do it. I have already had to re-install Windows 8.1 once from a USB Recovery drive which was not fun. So how to do it and get it done. I love windows 7 Pro but I can't figure out how to do it.
I have already turned off secure boot in bios. However, UEFI mode is still active vs legacy bios which is the other mode I have.

I'am trying 8 hours now to install Windows 8 to an Acer Aspire 5920g.
Problem is that when the usb flash drive comes to hdd presenation point the hdd isnt being displayed.
My guess is that Sata AHCI/IDE controller driver for the 5920g's chipset is missing from Windows 8 installation dvd.
I googled very much and i can only find XP and Vista Sata Drivers while oi need 8's.
Is there an alternative? I must get 8 installed in that laptop.

Friend of mine had a dual boot of windows 7&8 then, he tried to remove windows 8( it's partition was active but windows 7 wasn't active), he first deleted Windows 8 from msconfig then tried to delete the partition of windows 8( but Disk management didnt allow him neither easeus partition manager did, so he tried to keep windows 7 partition as active using easeus manager, then after completing the action, the PC failed to start, he tried automatic repair,but that bore no fruit... the PC says " Couldn't find any operating system, press ctrl+alt+del to restart...
edit: my idiotic friend after removing windows 8 from msconfig,upgraded win7 to Windows 8... suspect that MBR software has been corrupted... so is there any way to make his PC , boot again and remove the windows 8's( previously clean installed) partition ...

I have a multiple operating system and used to get the blue graphical boot menu with a rectangle with the name of each operating system in it. After a few boots it went back to the text menu, and only returned a couple of times. Is there a way to get the graphical boot menu back permanently? It looks a lot nicer. I have XP, Vista, 7, 8, 8.1 .....

Yesterday, I clean-installed Windows 8 Pro x86 on an old Dell Vostro 1400 laptop which had been running Windows 7 Ultimate, and it activated and ran fine, without even a single exclamation point in Device Manager. I applied the update necessary to make the Store offer 8.1 and proceeded to install it as I've done on a couple other machines. After downloading the thing, it errored out with:
Couldn't install Windows 8.1
Contact your PC manufacturer to see if you can upgrade the System BIOS
When I clicked the OK button, it then gave me the informative and grammar-challenged error box:
Something happened and the Windows 8.1 couldn't be installed. Please try again. Error code: 0xc1900104
Try again Cancel
Ever the optimist, I clicked Try again, and of course, it proceeded to download all over again from scratch, only to error out in the same way. I then downloaded all the Windows 8 updates, although just the one had been necessary on my other machines that successfully upgraded to 8.1, and tried again, only to get the same result.
Today, I've discovered the Windows 8.1 Compatibility Assistant, which avoids the lengthy download of the upgrade every time (Microsoft, maybe you should run it implicitly before downloading 3 GB of transient data), and it tells me:
This PC doesn't meet system requirements
Contact your PC manufacturer to see if you can upgrade the System BIOS
Obviously, no BIOS updates are available, and what exactly is the problem here with my BIOS. The obvious googling turned up nothing except some people with Sony Vaios that had the same problem, which was corrected with a BIOS update, and of course, there is no information on what their BIOS update does to make the 8.1 upgrade possible.

My PC is a dual boot system which had Win XP on disk1 and Win 7 on disk2.
When I installed Windows 8 several months ago, I chose to install it on disk1 and completely remove Win XP.
Everything works fine but my log-in screen now contains 4 start-up tabs instead of just 2 (see below):
Windows 8
Windows XP
Windows 7 (volume 1)
Windows 7
The only tabs which are valid are Windows 8 and Windows 7 (volume 1), the other 2 are non functional. How can I edit this screen and remove these tabs?

I have an Acer aspire S3 Ultrabook Laptop (one of several laptops) and I am wanting to upgrade the os to win 8 pro. I have the win 8 pro pack,which is a full version i think,it does not say it is an "upgrade". Am i still able to use this win 8 pro pack to upgrade?( i thought upgrade packs are in fact cheaper)
There is the windows upgrade anytime link which i used just now,but it said that the windows key is invalid.It is a brand new pack with a new key.
I have read instructions online that say i need to insert the disk.But i am wondering if all the acer software will be deleted on C drive,although the instructions say it will be kept intact,as it has the acer recovery software in control panel on it. If the acer software is deleted how will i reinstall those? I am guessing that the win 8 pro disk will have all the right drivers?

Been running this system since 2010 win7 and upgraded to win 8.
When I switched over to win 8 I also bought an ssd drive (C) and it seemed to be working fine ever since.
I recently bought a couple 3TB drives and wanted to replace the old HDD (F), installed the drives, transferred all data off F and then shut down the pc. I took F out of the pc and it won't boot.
Going from loads of tutorials on here I found that F was listed as active and a system drive.
Any attempts at making it inactive and activating C resulted in nothing. I used my startup repair disc but there was no OS listed to repair??
Whenever C is active and F inactive, I've no options at all with startup repair.

I upgraded to 7 to 8 Pro using usb to do clean install. I want to reinstall again from usb and change the system language from French to English as not everything comes up in English by changing language settings. Device descriptions, system accounts, bitlocker screens are still French.
Is this possible? When I try the installation instructions are in French. Do I need an English ISO or can I change the one I have?

I am currently typing on a Acer Aspire 6935. It originally came with Windows Vista Home Premium and then I bought a copy of Windows 7 Ultimate. It took me a while and when I say a while, I mean about 10 weeks to find ALL of my correct drivers and this laptop is special because it has some fantastic speakers. So finding the right driver for the speakers was a pain in the... Without the drivers, my sound horrible. I want to upgrade to Windows 8 because I like the new interface and I like Windows 8.1 Update 1, however, my drivers are a problem. I found the correct drivers but I forgot where I downloaded it from. What can I do? If I upgrade to Windows 8, will it keep my drivers?

My system started pausing/freezing, log files showing some errors about not finding some *.dll files. The system will still boot; I enabled the administrator account, but have lost the original user profile. All the docs/files are still there in the usual c:usersusername... directories. Installed Seagate's SEATOOLS app and it reported a failure, not completing the process. I used the recovery app from Acer and created a bootable recovery device (Seagate expansion portable drive) and a CD of drivers and apps. I am told this system has a small SSD, but it is hidden because it is for the OS, Windows 8.
I've put an identical replacement drive in; I changed bios to boot from the external USB device and it comes up in what appears to be recovery mode. I select option to completely refresh system, but it then comes up with "drive where windows is installed is locked". I select the reset option, it asks whether I want to re-partition. If I select yes, it returns 'unable to reset pc system drive cannot be found'. If I select no to repartition, it returns 'unable to reset. A required drive partition is missing.'
Using the recovery app, I can get to command prompt; it comes up as windows ver 6.2.9200, x:windowssystem32, The c: dir<enter> command returns efi (D), bootmgr, boot (D), bootmgr.efs and sources (D). I insert another usb stick and those files show up correctly.
Also, a byproduct of installing drive it indicates it can't find a battery now!
Why the reset or recovery options are not able to see the replacement drive? Since I used a Seagate expansion portable drive rather than a 16gb USB drive, is that the problem? I believe Windows 8 won't allow the use of a DVD for the recovery process (size issue?).
Could I consider doing a reformat and clean install of Win7 pro? Will I need to change the boot bios setting from UEFI to legacy? Would I still be able to reinstall Windows 8 at some point in the future if necessary, or should I try to work with the Windows 8 configuration?

I have a Acer Aspire E1 570 laptop that I use for college, the laptop is less then 8 months old. For some reason recently it starting going dead at 40% battery charge remaining. I ran a powercfg -energy from the command prompt and it said that my batterys designed charge is 37000 and last full charge untill the battery read it was fully charged is 36526. I use the laptop on the battery all the time while i'm at school. I was thinking maybe just refresh the PC from the recovery i made using the provided software with the computer. I'm unsure if that would correct the issue.
