My system was configured to dual boot Ubuntu 12.04.1 LTS and Windows 7. Today I got my hands on the MSDN release of Windows 8 and I installed it over my Windows 7. Now the computer just boots to Windows 8 directly without loading the GRUB screen.
How can I pick which kernel GRUB2 should load by default? I recently installed a the linux realtime kernel and now it loads by default. I’d like to load the regular one by default.
I recently bought a new Laptop:
Lenovo IdeaPad 320e
Intel i5 7200 2.5GHz processor
8Gb RAM
2Gb NVidia 940mx Graphics
1TB HDD
I have my encrypted Archlinux installed on my SSD. Now I have one HDD with Windows installed. But in my GRUB just Archlinux is shown (no Wonder, because I just installed Windows on the other HDD, GRUB doesn’t know of that by now.).
I’m running a headless server installation of arch linux. The high rate of kernel upgrades caused me some maintainance headache and I therefore wish to switch to the lts kernel.
Every time update-grub is run all hard drives are scanned. Each drives that is in standby state will spin up to go idle. This is a waste of energy. We use update-grub version 1.98:
I had troubles with the screen brightness control in my laptop and I fixed it by adding the acpi_osi=linux and acpi_backlight=vendorparameters to the filegrub.cfg.
I’d like to know what these parameters mean and why they work.
I am using 3.2.0-4-amd64 #1 SMP Debian 3.2.46-1 x86_64 GNU/Linux Debian GNU/Linux 7.1 (wheezy) Release: 7.1.
I currently dual boot Windows 7 and Fedora 14, using GRUB, with Windows 7 as my default. I know that from Fedora, I can set GRUB to boot into Fedora, overriding the default, on the next reboot. Is there a way to do this from Windows? That is, can I change the GRUB configuration permanently or semi-permanently from Windows so I don’t have to be in front of my computer to boot into Fedora?
As a Linux newbee, I would like to know What exactly is the significance of “Quiet Splash” in GRUB?
