I'm having some trouble with dual booting CrunchBang on my laptop with windows 7; whenever I select it from grub it appears to be booting, but the screen then goes black and I am unable to do anything. The laptop has switchable graphics with Intel integrated and an ATI 5650. I have tried entering nomodeset into grub, but it didn't seem to recognize it or do anything. I was able to use CrunchBang from my live USB before, but only with the failsafe mode as the regular would have this same issue.
Any help is greatly appreciated! Thanks!

I had a similar issue with booting switchable Intel/ATI on openSUSE12.3. I can't promise you it'll work, but I used the bios to set the ATI as the only GPU...and it "just werks (tm)". It isn't the cleanest answer, but will quickly let you know if it's just the kernel modules not getting along with switchable graphics.
Okay I tried to do that, but it unfortunately had no effect on the issue. So maybe it's not specifically a problem then with the graphics themselves?
this is just a shot, but try booting with acpi=off

You can use sudo into: /etc/default/grub. Append the line that you wish to change there (it looks just like the grub menu.)
After that, run (from terminal):
Should make your change permanent.

Okay I just tried that, and put apci=off after "quiet" in the grub text file. It didn't really look like the menu though, and it didn't seem to affect anything after updating. I just restarted and now I'm unable to get back in at all. I am in recovery mode and have a line of root@crunchbang:~# now on a screen saying root account is locked, starting shell.
Unsure what to do now...Also the laptop is running significantly hotter just staying on with crunchbang.
O_o okay, I'm going to see if I can replicate your problem by borking the kernel boot parameters and then repairing the setup. Hang with me. I'm pretty sure that you can use "sudo passwd root" to give root unlocked account.
I turned it off as I wasn't able to get anywhere with it, and am trying to reboot the same way as before. Now it only provides a black screen from either option and I cannot return to the command line I had before....
Okay, so adding
To /etc/default/grub worked fine for me. Is that what you did? Also, explain to me in detail how the boot process is working. Are you reaching Grub? If so, you can always use the "e" option to remove whatever you've added to the grub kernel parameters.
That is exactly as I did, but it did not change the line in Grub for me at all when I looked at it using e.
Although now I am unable to put the same line in and boot into crunchbang. It just creates the same black screen as before I put the line in.
Just tried it again and it is now checking the file system. I think it might boot once it finishes its check which may take a few minutes
Yeah it booted and in my grub file it says exactly as you typed. GRUB_CMDLINE_LINUX_DEFAULT="quiet" acpi=off
But I updated it before through the terminal and it didn't stay in grub itself?

Okay, assuming that you get a boot out of it...this is the way to make the change permanent. Exactly. Step-by-baby-step.
In a terminal, type:
sudo nano /etc/defult/grub
Edit the line to look like:
Press (Ctrl + x) to exit the nano text editor. It will ask if you wish to save changes, press "Y" to tell it yes. It will ask if the /etc/default/grub file is the one you wish to save to, and you must simply press "Return" for it to save. Then, type into your terminal prompt:
and enter the password for sudo privileges. It should tell you that it's "Generating grub.cfg" and identify all kernels on mounted devices. (If only Crunchbang is installed, you'll only get a single vmlinuz and initrd).
Now, you should be able to reboot with permanent changes to Grub.
Just followed your instructions and it's working perfectly now.
Everything boots happily!
I can't thank you enough for helping and at the same time dealing with my ability to not be able to do simple things!
