Have you ever tried to install Windows 64bit on your mac? If you have done so, you already know that the process of installing and running Windows 64bit is absolutely fine. Then you have to install Apple’s drivers from your Mac OS X dvd. According to Apple, only a few intel based models are capable of running 64bit Windows which is not true. The list of apple computers capable of running 64bit Windows, which is originally published by apple is the following (http://support.apple.com/kb/HT1846): MacBook Pro (13-inch, Mid 2009) MacBook Pro (15-inch, Early 2008) and later MacBook Pro (17-inch, Early 2008) and later Mac Pro (Early 2008) and later iMac (21.5 inch, Late 2009) iMac (27-inch, Late 2009) iMac (27-inch, Quad Core, Late 2009) MacBook (13-inch, Late 2009) etc Unfortunately, before the driver’s installation begins you may receive the following frustrating message: Here is the solution to your problem.

Operating System not found – Possible Solution

Operating System not found – Possible Solution

Posted by on Dec 10, 2009 in Posts | 0 comments

I was playing with a partition manager application in order to create a new partition on my single hard drive. After restarting my PC, Windows 7 couldn’t boot. The error message “Operating System not found” was shown and the only thing I could do was to shut down the PC. After a few searches on the web I discovered that the reason for this problem might be a faulty hard drive. But in my case, I was sure that the hard drive was not faulty because firstly, my PC was only 2 weeks old and secondly, I was previously playing with a partition manager application which might cause inconsistencies to the hard drive. Hence we conclude that the problem might be a broken Master Boot Record (MBR). Here are the steps followed to fix this problem: 1 Insert Windows Vista/7 DVD and boot from the DVD drive. 2 At this screen choose to install now. 3 Select your language and click next. 4 Select the radio button for “Use recovery tools” and click next. Note: The system might not be able to locate your Operating System as shown in the figure because of a broken MBR. 5 Then select “Command Prompt”. 6 In the command prompt, enter the following commands: DISKPART LIST DISK The command “LIST DISK” is used to display the number assigned to your hard drive. This number is needed in the next step. For example, hard drive is disk 1. SELECT DISK 1 LIST PARTITION The command “LIST PARTITIONS” is used to display the number assigned to the partition where Windows Vista/7 is installed. For example, in my hard drive, Windows is installed in partition 2. SELECT PARTITION 2 ACTIVE The command “ACTIVE” is used to mark as active the primary partition of the drive you want to boot from. EXIT BOOTREC /FixBoot The command “BOOTREC /FixBoot” writes a new boot sector to the system partition by using a boot sector that is compatible with Windows Vista or Windows 7. BOOTREC /RebuildBcd On the question “Add installation to boot list?” type y and press enter. The command “BOOTREC /RebuildBcd” command scans all disks for installations that...
