[SOLVED]GRUB Dual-boot problem

Hey guys, I need some help since I haven't had any issues with GRUB until now. I've read the GRUB page on the wiki and several other sites, but I'm still not sure which method I should use.
Anyway, everything was fine yesterday, I could boot into both my Windows and Arch. Then for some reason today, I tried booting into Windows, but stated BOOTMGR is missing, press CTRL+ALT+DEL to restart. So I tried booting into Arch, which was fine. So I used the Windows CD and then used Startup Repair to fix Windows, but unfortunately it didn't work. I then typed bootrec /fixmbr (which was typed impulsively, since I use that whenever I uninstall Linux). Anyway, that makes Windows overwrite to the MBR, so after booting my laptop it goes straight to Windows.
So I was wondering whether to use the method where you have to use chroot, the method you can just use grub> find /grub/stage1 and install to MBR, or just run through the Arch install CD and skip everything except installing the bootloader and rebooting.
Replies are appreciated, thanks in advance.
EDIT: Solved it. I booted in the Arch Linux install CD and followed the instructions on the wiki. I switched to the grub shell and used
grub> find /grub/stage1
for use in root. It displayed (hd0,6), so I then used
grub> root (hd0,6)
. Lastly I used
grub> setup (hd0)
to install GRUB to the MBR. It works perfectly again.

I know exactly what the problem is.
If you're using rEFIt, sync your partition tables (should be the menu item called 'Partitioning Tool'). The problem is that GRUB has been installed, but doesn't know where to find the Arch partition.
After syncing, you may find that the boot process hangs at the Linux logo on a gray background. No worries — just reboot and the problem should fix itself.
N.B. You will need to do a partition table sync every time you change your hard drive's layout.

Uninstall Linux and Grub dual boot from Win7 HP dm4..

uninstall Linux and Grub dual boot from Win7 HP dm4. I only have recovery disks. I just want to do a Startup Repair not a full system recovery.
When I reboot with the recovery disk there is no choice for Startup Repair.
thank you for any help.

Hello bluecape. I understand you'd like to uninstall Grub/Linux. Is your recovery disc a Windows Recovery disc or the HP System Recovery disc?
You will need to begin by fixing the "Master Boot Record." This is where Grub is installed and what allows you to select your operating system. If you have a HP System Recovery disc the steps may be different--these steps are specifically for a Windows Recovery Disc. Try the following.
Boot the notebook with your Recovery Disc.
Select "Repair your Computer."
Select your Windows version once the dialog box populates.
Choose "Command Prompt" as your Recovery Tool.
From the command prompt type "bootrec /FixMbr" and press Enter.
Once this is finished type "exit" and press Enter.
Take the disc out and reboot the PC. It should boot straight into Windows without a boot loader prompting you.
The Linux files and partitions are still there but you can now remove those partitions from Windows. Simply format the partitions to "uninstall" Linux.
I hope this is helpful. If you have further questions just let me know. Have a great day!

Funny, I have an HP Laptop that dual-boots Vista and Arch x86_64. I don't seem to recall having a problem. I installed Vista first (system restore disk <yech!>), then used gparted to resize the Vista partition, then did a standard Arch install.

[SOLVED] GRUB not booting up properly.

So. I have had a dual boot of Windows 8 and Arch for awhile now. Everything went very well until I decided to add Fedora to the mix. It installs another GRUB, and there looked like there was no way to select Do Not Install Bootloader in the install. So, after that, I went into Arch to uninstall Fedora's GRUB install. That's when the problems arose. I deleted anything that looked like GRUB in /dev/sda9 (The Fedora partition) Then, when I rebooted, after the Gateway logo, it shows me a Shift UEFI Key configuration thing, and says Booting in 5 seconds, then when the countdown ends it displays the horrible Boot disk not found system halted error. I know there's still stuff there as if I smash F12 at boot, I can select grub from a list of things and select Arch, Windows, or Fedora from grub. But its very annoying to have to smash down the F12 key everytime I reboot. Anyone know to fix it?

Load the Arch live ISO, mount your Arch partitions, use `arch-chroot` and post the output of:
lsblk -f

Windows 7 & 8.1 Dual Boot Problem

In my pc dual booting system is generated.
Both os windows 7 & 8.1 are separatly partitioned.
I have used it several day,but during 2 days windows 7 has been disrupting.
For that,i have only formated & reinstalled windows 7.
But now i can see that windows 7 is directly started but there are no options for windows 8.1 after opening my pc.
At early days options for both 8.1 & 7 can be seen.
But now that can't be seen.
Only windows 7 is started directly.
I have tried a lot,but can't understand the problem.
Please help me....

Hi,
Please using the command below to fix system boot loader for test.
Open Command Prompt with administrator.
Type bcdboot x:\windows, press Enter.
After that, restart your computer to check if problem resolved.

Windows 7 and Arch linux dual boot problem

hey guys I had an issue with windows 7 dual booted with arch and i was just wondering my windows 7 crashed. I had Reinstalled windows OS and all my partitions are set up but now when I try to boot up arch I cant at all cause windows Boot took over and i have no way of getting into arch is there anyway i can fix this or maybe reinstall arch without loseing my home folder with all my data, or is there just and easyer way to fix this issue im stuck. thank you all for your support as i am a noob

You need to re-install grub. When you reinstalled Windows it will overwrite grub preventing you booting Arch. You'll need to boot from a liveCD and chroot into your Arch installation. details for recovering grub are in the wiki - https://wiki.archlinux.org/index.php/GR … stallation

(Grub) Dual booting with XP on sdb

My goal is to be able to dual boot with two hard drives: Arch on sda and Windows XP on sdb. With help in the #archlinux IRC I've managed to get Windows XP to boot by getting the menu.lst correct but when I click "Start Windows Normally", or "Start in Safe Mode", etc. etc. the computer just reboots. A cellphone picture of that all well known Windows black Screen: https://www.dropbox.com/s/nrczq86vsi6o9 … 6%20AM.jpg
My fdisk -l and /boot/grub/menu.lst:
http://pastebin.com/sLUUsCcU
To see if my xp hard drive was still intact I did this:
sudo mount /dev/sdb1 /media && ls /media/
and saw this:
boot.ini NTDETECT.COM pagefile.sys System Volume Information
Documents and Settings ntldr Program Files WINDOWS
nano /media/boot.ini

Default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[Operating Systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows" /noexecute=optin /fastdetect
I've consulted all the wiki's and forum posts I could find but at this point, I'm just stuck. Somehow I think the final result is me reinstalling both OSs and starting again from scratch.
Any help or advice on getting a fully functional Windows XP on /dev/sdb would be greatly appreciated

Pres,
Thanks for the post. If I click "Last Known Configuration" the computer just reboots and I'm back where I started. Yeah, my Arch is working fine. My thought process behind re-installing Arch was that maybe the installation process would deal with the Grub config of /dev/sda and /dev/sdb automatically somehow and make everything OK...

Dual Boot Problem

I'm trying to dual boot widows xp and arch. I have everything setup except i cant get grub to start when i turn on the system. All it does is boot into xp. I've read the wiki and everything and it didn't help. Thanks

notice I have several drives only two have os's arch32-sata arch64-sata arch32-ide & xp-ide
on my system to boot off the ide drive I have to tell the bios to boot from it
on each drive it has its own grub & on each grub both say to boot arch it looks to /dev/sda2 you see when I tell my bios to boot the ide it then makes it the 1st drive. so in the initrd file I tell it to load modules for pata only this way arch sees it then as sda not sdc as it is label in my fdisk -l posted above
I hope you understood what all I put here. if your like I was when I first migrated to arch I said its english but it sure seemed a foreign language.
when/if you have multiple os's & partitions & drives it can be a pain
you say your following the wiki but are you absolutely positive xp is where you tell grub it is
cause if you tell grub xp is on sda1 & sda1 is a hidden partition that was setup at the factory & xp is actually on sda2 grub is not going to look at sda2 only at sda1 that you told grub xp is there
linux can be frustrating in the begining especially arch. I remember, but it has been a fun learning experience & still is.

Ethernet dual-boot problem

My new onboard ethernet - Realtek PHY RTL8201CL on an ASRock K8NF4G-SATA2 board - seems to have a strange problem with dual-booting. After I've booted Windows XP it refuses to work in linux. My system hangs for a time during bootup at "Network" and finally moves on after network has registered as failed.
The only solution seems to be to turn-off the computer and truly power it down (unplug it). Once I've done that everything seems to work again without any trouble. I believe it must be the ethernet since this didn't happen with my old computer using exactly the same ethernet ADSL modem.
Since I don't use windows often it's not a big problem for me, but it is an annoyance. Does anyone know what might be causing this?

weird, not that related but i remember an issue with ati users where starting windows first was necessary to initialize the ati card; thus getting it to launch in linux...
maybe you can alleviate this by having some initialize down/up code in your startup code before 'network'.

Dual Boot Problem - Mountain Lion / Lion

I recently tried to setup a dual boot between Lion and Mountain Lion. I have them both existing on seperate internal hard drives. I can boot into each other just fine by selecting them from "Startup Disk" under system preferences. However, I cannot boot into them by holding down the option key at startup. When I hold down the option key at startup I just get a grey screen that hangs there. No options appear. It just freezes.
Any ideas on what I can do to make this work? Both operating systems are installed, working, and bootable. I'd just love to be able to have the option to choose which one to boot into at startup.
Thanks!
I should also add that I have tried zapping the PRAM as well.

I have some new information on the problem. Alternative boot options do appear after holding down the option key, but it takes a solid minute and half for them to appear. I guess I was not waiting long enough. Any reason as to why it is hanging for a 1 1/2 minutes before displaying the boot options?

/dev/sda1 used to be Windows 7 EFI partition. Gparted says it is flagged as boot.
What I did to install arch:
Partitioned /dev/sda5 with windows disk manager to create linux partitions and formatted the new partitions with gparted as the noob I am.
created /dev/sda6 for EFI boot
created /dev/sda9 for boot partition
created /dev/sda10 as root.
Did not touch
/dev/sda1 which was the EFI partition named SYSTEM
/dev/sda2 which was windows boot partition
/dev/sda3 which was windows C:,
/dev/sda4 and /dev/sda7 which I don't know what they used to be (possible for Asus fast wake up or swap whatever)
/dev/sda8 which is recovery partition.
I did not touch any grub files, except /etc/default/grub

SOLUTION:
first I needed to mount Windows EFI partition which was /dev/sda1, so :
mount /dev/sda1 /mnt
Then issue the following commands and take note of the outputs:
grub-probe --target=fs_uuid /mnt/EFI/Microsoft/Boot/bootmgfw.efi
which outputs: 18DF-E58E and
grub-probe --target=hints_string /mnt/EFI/Microsoft/Boot/bootmgfw.efi
which outputs: --hint-bios=hd0,gpt1 --hint-efi=hd0,gpt1 --hint-baremetal=ahci0,gpt1
Finally edit the os-prober entry to the following in /boot/grub/grub.cfg
menuentry 'Windows 7 (loader) (on /dev/sda3)' --class windows --class os $menuentry_id_option 'osprober-chain-5246C0D846C0BE4B' {
insmod part_gpt
insmod fat
insmod search_fs_uuid
insmod chain
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt1 --hint-efi=hd0,gpt1 --hint-baremetal=ahci0,gpt1 18DF-E58E
chainloader /EFI/Microsoft/Boot/bootmgfw.efi

grub-probe --target=hints_string /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi
--hint-bios=hd0,gpt1 --hint-efi=hd0,gpt1 --hint-baremetal=ahci0,gpt1
Sorry, no need to anymore. Thanks anyways.

[Solved][GRUB/ATI] Video problem

Hi all.
I have a Radeon HD 6670 (Turks XT/r600)
When I boot arch linux live from USB everythink works ok.
But after install I have no video.
System boots > shows grub > shows systemd things > screen blinks and all black.
After some self research, I found "gfxpayload=keep" on grub parameters and change it to "gfxpayload=disable", then F10 and everything works great (video/X/VDPAU/3D...)
Why it hapens and how can I permanently set this disable on grub?
[EDIT]
Some PC, some instalation, with on board HD4250 (RS880G) video works with gfxpayload=$ANYTHING
[EDIT 2]
You can change gfxpayload on /etc/default/grub

After which you run '# grub-mkconfig -o /boot/grub/grub.cfg' and the changes are saved.

[SOLVED] SSD and boot problem

I recently bought a new 30GB Corsair SSD, and it runs wonderfully. However, the device takes a considerably long time to initialize on boot (~30-45 seconds).
Here's a snippet of the relevant dmesg output:

I haven't encountered this problem with any other drive I've put in there, so I'm guessing it must be SSD-related. Has anyone else experienced something similar, and could you point me in the right direction? Thanks.

Do you think it's defective/worth replacing? It's more of an annoyance than anything, and the drive has no other visible issues other than on initialization.
Yes, I do. Healthy drives don't timeout on simple DMA initialization requests.

Dual boot problems 10.3.9 and 10.4.6

I have a power mac G5 with 2 internal hard drives. The primary drive is running 10.3.9. I just installed 10.4.6 on the secondary hard drive. Ever since, the computer boots from the secondary drive and the primary hard drive will not mount. it won't come up as a startup disk in the system preferences, it only appears in the system profiler and disk utility. in system profiler, the partition is greyed out. in the disk utility, disk repair reports an error: invalid b-tree node size, which it is not able to fix. (read on as the drive atually works). when i disconnect the secondary drive, the primary drive running 10.3.9 boots and runs. i swapped the drives, moving the secondary as the primary. no change. i need to keep both systems running until i can update all my software. why is it that whatever both drives are connected only the drive running tiger ounts? any help? thanks!
power mac g5 Mac OS X (10.4.6)

try booting up from your installer dvd, and choose startup disk from off the cd - see if they both show up.
