Has my Debian installation disabled hibernate in Windows 7?

[lindsey]

I've been reading this issue up in forums and some observers have suggested a link to dual-booting. However, I've never had this problem before and I've made many Linux installations alongside Windows before while maintaining the hibernate function in Windows. Does anybody know why I lost it this time?

One of the differences with this particular installation is I am not sure if GRUB was installed to the MBR or to the linux partition. A) How would I check? and B) would reinstalling GRUB to the MBR if it is not already, restore hibernate on the Windows 7 side?

The exact syptoms are when I click or issue a command hibernate on windows, I get logged out instead.

This isn't a Windows problem however, and more likely than not, it was my Linux installation which caused it.

System: Deb 6 testing 32 bit, dually running with Win 7 32 bit Ultimate

Theories and solutions?

If the grub menu is in the first thing you see when you start up, then it's in the mbr. grub/grub-pc should then be able to chainload through to the windows bootloader... in short: it's not an issue.

I cannot see how any of this would affect windows hibernation however as when a system hibernates it does not reboot or process the boot sector at all - though I know little about modern versions of windows or how they handle this function. Short version: debian is not to blame.

The only thing I can think of is that after partitioning and installing debian you now do not have enough hard disk space available for a suspend to disk... but this is not exactly debian's fault. Short version: windows problem.

That sounds fair enough but I keep reading all over the web that there may be a solution which involves resetting GRUB somehow... For example, what do you make of this: [SOLVED] GRUB + Windows 7 = Can't put windows to sleep/hibernate - Ubuntu Forums

As I said, I know nothing about windows 7 or how it handles hibernation... you could try some of the solutions in that thread. If grub is installed to the mbr, then you may instead want to reinstall it to the / partition for your debian install and then restore the windows bootloader (there are hundreds if not thousands of threads on the butnut forums for this...) and set that up to chainload to grub.

I read the link you posted to the Ubuntu forums. The solutions for the posters were to mark either the boot or system partition on windows as active which has nothing to do with Grub. A windows partition needs to be marked as active in order to boot and a Linux partition does not.

This did it for me: [SOLVED] GRUB + Windows 7 = Can't put windows to sleep/hibernate - Ubuntu Forums. For some reason you needed to set C: as the active partition on Windows. If anyone can explain please, do.

Since the solution to the problem as posted in your link all involved setting one of the windows partitions as active, I would think you might have better luck getting an answer at a windows forum since it is unrelated to Grub/Linux.
