Pressing CTRL+ALT+DEL reboots the computer. I can't change the boot priority. I have tried removing my CMOS battery but it doesn't change anything. Bruce's reply: Depending on the BIOS used by the system, the error message that appears could also be "Missing operating system". There are both hardware and software issues that may be causing either of these error messages to appear which we will look at in turn. Is your hard drive detected by the BIOS? There is the possibility that the connection to the drive has been jarred loose. The documentation for your device available from the Acer website is next to useless and I cannot find a decent shot of the underside of the computer but there should be a means to access the hard drive of your computer via a covered opening without resorting to major disassembly. On most laptops it only requires a small Philips screwdriver to remove it. Just open up the cover and ensure the drive is firmly seated in the connector. If the drive is securely connected, you may have a failed hard drive. In this case, t

Operating System Not Found Windows 10
their Windows computer. If you frequently get these messages while booting Windows 10 operating system not found dell / 8 / 7 / Vista, then this post will guide you in the proper direction. Missing Operating System Not Found In operation system not found most cases, this happens when you install Windows Vista or later operating systems in conjunction with older operating systems. For example, Windows XP used Boot.ini and Vista onwards it was BCD Edit.exe located in http://www.makeuseof.com/answers/how-do-i-fix-a-computer-that-says-operating-system-not-found-when-booting/ Windows\System32 folder. There can be two scenarios here. Advertisement ^ First you install Windows XP or prior operating systems and then install Windows 10. In this case, the BCD Editor may take over and remove boot.ini. This makes the computer believe that there is only one operating system installed and that is Windows 10. Such issues can be fixed by running BCD Editor (Boot Configuration Data Editor). Maybe http://www.thewindowsclub.com/missing-operating-system-not-found-windows you installed Windows 10 first and then you went on to install Windows XP. The boot loader of Windows XP is made default and you won't find Windows 10 in the list of operating systems. In worst case scenario, you won't find any operating system as the boot loader is corrupt due to conflict of both boot.ini and BCD.exe. This situation too, can be fixed using BCD Editor. You just need to know how to add the operating systems to the boot loader and most importantly, assign them each, a different drive letter. You will need to boot with the disk, and repair Windows. Here is what you can try. Boot the Windows 7 or Windows Vista DVD, choose Repair and then Open a Command Prompt window. Now enter the following commands one after the other and hit Enter after each: bootrec.exe /fixmbr bootrec.exe /fixboot bootrec.exe /rebuildbcd Reboot your Windows system. This should hopefully and have made your problem go away ! For more details see KB927392 and read this post on Bootmgr is Missing in Windows 8.
