I just switched from Fedora 16 to 18 (not an upgrade but a clean install). Previously in Fedora 16, I had no problems doing a Fedora 16 and Windows 7 dual boot in EFI mode. Grub Legacy (EFI version) worked perfectly. Now with Grub2 (EFI) there seems to be no working chainloader command.
I can still boot Windows if I go into the BIOS boot menu and select it.
Original title: How can i solve (un)booting windows 7 on the same partition with grub?
I've been researching for 2/3 days about this problem and I have came up empty.
Basically, partition 1 is Windows 7 and partition 2 is Ubuntu 12.04. I told Ubuntu to install into partition 2 and to install grub on partition 1 and that works fine. But the problem now is that I can't boot to Windows 7.
Hi there,
Yesterday I have installed the latest version of Fedora. Fedora works fine, but my windows 7 install is not available on the grub menu.
So I had the perfect Ubuntu 12 / Windows 7 dual boot set-up -- until I had to re-install Windows 7.
After the deed, GRUB2 was of course wiped out, thus my Ubuntu installation is rendered inaccessible.
I have tried these steps:
mount /dev/sda5 /mnt #This is where my Ubuntu installation resides.
mount /dev/sda1 /mnt/boot #Indicated by the `*` under `Boot` when doing `fdisk -l`
mount --bind /mnt
I installed GRUB2 from ArchLinux, which allows me to dual-boot between it and Windows 7. I have the entry for Windows manually rather than using the "os-probe" tool.
When I boot my laptop, the GRUB loading message generally takes around 5-7 seconds, which isn't the worst but it is noticeable when I have to restart Windows to update or something like that.
I had fedora 18 and then I installed windows 8 afterwards. I now cant boot into fedora because grub was replaced by the windows bootloader. I created a f18 live cd and opened a terminal.
I've Asus UEFI motherboard with 2 hard disks, let (hd0) and (hd1). I managed to make my Debian Wheezy on my second disk bootable using grub-efi and it boots ok. I also have Windows on the first disk, which isn't unbootable but the way I have to do it is unconvenient.
These instructions explain how, with GRUB v1, to make it possible to choose which OS will boot next, either from Windows or Linux, by redirecting GRUB to look for a menu.lst file on a separate FAT32 partition. Either Ubuntu or Windows can then modify that menu.lst file to determine the next OS that will boot.
Does anyone know how this could be done in GRUB2?
Ive been running a dual boot set up with Vista for a while (I usually mess things up when I update suse :P)
I left boot options at the default which was my initial mistake, but basically i think grub was installed at the mbr. In other words i didnt have the windows boot menu.
