View Full Version : lost windows in System Preference/Start Up

12-11-2011, 11:05 PM
IMAC 27" one year old with LION. Had WIN 7 installed with Bootcamp and worked for months OK.
Now no longer shows Windows disk in options when I go to System Preferences, Start Up Disk - it just disappeared.

Can use the Option button on a USB keyboard when powering on to select
Windows 7 but the wireless keyboard (aluminum) will not do it.
Hate to have to use a separate USB keyboard to get into Windows when
it used to work just fine using the selection in Start-up disk for rebooting
in Windows.

How can I get the Windows disk back into the Start up options?

Any suggestions? Thanks.

This can be tricky - I ran into myself once with a certain version of Paragon's NTFS for Mac. Did you happen to install any third party NTFS drivers?

For a quick and simple fix, try QuickBoot (http://quickboot.en.softonic.com/mac).

thanks for your tip - I downloaded and installed Quickboot but the result is
unfortunately the same: The Windows disk partition is not visible in the
choice of drives to boot from. Thus I can reboot the MAC LION disk with
it but still can't get to WIN7.

Very frustrating - if at least the bluetooth keyboard would work with the Option key then I would not need two keyboards on the desk.

The next time you boot the machine in Windows, run a CHKDSK on it.

Using Windows 7, how do I run CHKDSK? - Microsoft Answers (http://answers.microsoft.com/en-us/windows/forum/windows_7-performance/using-windows-7-how-do-i-run-chkdsk/a68b3e4d-1a42-e011-9767-d8d385dcbb12)
