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!

ATI display driver lost with Linux and XP dual boot os

I brought ThinkPad W500 with windows vista. I want to get rid of the hidden boot system reserved partition and downgrade to windows xp and install OpenSuse os. Following some sourses found on the web, I first set the bios sata ahci mode to compatable mode. Then install windows xp and update the sata driver. Restart and reset the bios sata back to ahci mode. It works fine with windows xp and I install back all driver. Finally I install OpenSuse and create dual boot with Grub.
But a serious problem come up with me. Everytime after restart from the linux os and back to windows xp, xp doesn't regonize the ATI display divice and tell me no driver installed with low screen resolution. And I have to restart the machine and boot direct into xp for the second time and the problem gone. But it is so annoying of doing this everytime. Anyone can help? Many thanks.
Solved!
Go to Solution.

Hi stanleyimko,
I don't have an answer, just a couple of questions:
Does your W500 have switchable graphics? If so, you may have to turn off "let the OS detect" or permanently select one or the other in BIOS. XP isn't switchable aware, so I don't know why that would make a difference.
Do you see the problem on cold (re) boot to XP, or only on warm reboot from Linux to XP?
Seems like something is leaving your BIOS in an odd state (I guess that's obvious) and maybe a cold reboot would sort it.

Need some help about Win 8.1 and linux with a dual boot

Hi!
I have a Lenovo z50-70 notebook and I have a Windows 8.1 on it. (The one which was shipped with this notebook...)
My concerns are Intalling Linux as a dual boot and loosing Windows 8.1.
As I am not familiar to Win 8.1, the product key is in the ?BIOS? and there's a lot of partitions...
If I install Linux Ubuntu (latest version) as a dual boot by manually making the partitions, etc. and then if I lose my Windows 8.1 system, how can I get it back?
I've made a backup of the system to the portable hdd but I don't know can I restore it, as I have no win installation disc and I am not sure if i can restore win 8.1 from the backup by using random win 8 installation disc that I've made from the downloaded ISO (for e.g. Win 8.1 pro iso from internet)...
I need a Linux distro for developing my Android ROM but I don't want to lose that Win 8.1 OS from my notebook. So.. What should I do?

Did you do a full disc backup of the C: Drive using a backup tool other than windows? If you did, then the recover of that partition will be up to your backup software.
If worse comes to worse, you can use the novo button to restore your computer to what it was like when it came from the factory. But there really is nothing to worry about. Create your new partition and just make sure that you install Linux to that partition. Make sure it is not the same size as any other partition, that way even if the Linux installer does not show the volume labels, you can tell which partition you want to install Linux in just by the size.

[SOLVED]How to install Arch Linux UEFI to dual-boot?

Hey,
so I have a Lenovo G50-70 on which I want to have a Windows-Arch dualboot. I followed the Beginner's Guide, installed Arch but ended up with an inaccessible Windows. I could boot into Windows from the BIOS utility, but not from the gummiboot bootloader.
The guide said if I wanted to dual-boot, I must leave windows EFI partition alone, which I did. I have my Windows partitions set up the Windows way, with the system reserved and EFI and recovery partitions, and I have my Windows partition of course and a data partition. After that I have some unallocated space, on which I made the Arch partitions, /dev/sda6 as an ESP partition for the EFI files, /dev/sda7 as root, /dev/sda8 as swap and /dev/sda9 as /home. The install process went without any error, then I made some configurations and installed dosfstools & efibootmgr. After that, I installed gummiboot and ran "gummiboot --path=/boot install". After that I created the configuration files exactly like in the guide, unmounted the partitions, rebooted and saw that there's no (easy) way getting into Windows. So my question is: how can I install Arch to have a working dual-boot system?
Thanks for any help in advance!

Hey,
Writing to you on my working dual-boot with ArchLinux (Windows 8.1 64-Bit, UEFI)
So first step I've done is creating free space of an existing partition in the windows disk management (windows button and r and then type diskmgmt.msc). At this step, you have to record which partition your efi partition is (just take a look at your efi partition and remember the mb of this partition for later)
Then go into the uefi settings (bios) and disable secure boot as well as fast boot, otherwise it could cause data crash.
Boot your Arch Live CD and follow the beginners guide all the way along till you reach the disk management.
If you want to have swap, you can create yours right now, should be a primary partition of about 4gigs.
Next partition is gonna be your home, system partition (I've didn't created two partitions for home and for the system but you could do this as well as just go with one partition) this partition gonna be formatted in ext4
Next step, you have to mount your windows-efi partition in /boot/efi but don't format it dont remeber if it asks you how to use the partition but if so, just use as fat32.
After the disk management go ahead with your arch installation and follow the beginners guide. (Make sure you're using the grub bootloader)
After finishing the installation, restart your system, hopefully you will recognize the opening grub menu. (but dont scare, windows wont show in the grub menu at this time so you have to boot your arch)
Arrived in arch linux type the command
grub-mkconfig -o /boot/grub/grub.cfg
Reboot and your done with your Arch Linux, Windows 8 dual boot, hopefully

OS X and Arch dual-boot on MBP - bootloader error

I have a Macbook Pro 9,2, and I dual-boot OS X and Arch. My main Arch partition is encrypted with an LVM on LUKS setup, and my main OS X partition is encrypted with Firevault 2. I run the vanilla Arch kernel, and I use xfce as my DE. I use refind as my boot manager, and grub as the bootloader for the Arch partition. This setup has worked flawlessly for several months. I update my Arch system once per week, and last Sunday was a large update since xfce got a large overhaul (in terms of program and config files). However, since the update I cannot boot into OS X (I am posting this here instead of an OS X forum since no change occurred to the OS X system so the problem must be with a change to my Arch system).
When I attempt to boot into OS X, I am asked for my password to decrypt the partition, but then I get the following error message:
efiboot loaded from device: Acpi (PNP0A03,0)/Pci(1F12)/SATA(0,0)/HD(Part3.Sig698A

Error: Aborted returned from boot.efi

When I hit a key, I get taken back to the refind menu. If I choose OS X again, I get the same error. This cycle can be repeated ad nauseam. Booting into my Arch partition, on the other hand, works just fine, with one hiccup. While usability does not seem to be reduced, after I input my password to decrypt the Arch partition, and before I see the tty1 login, I (since Sunday) occasionally get the following error message that I have never had before:
19.636262] [drm:crypt_set_fifo_underrun_reporting] *ERROR* uncleared pch fifo underrun on pch transcoder

The "READ FPDMA QUEUED" line and those below it repeat a few time with different numbers following "cmd" and "res," but then after a few moments the messages clear off the screen and I arrive at my tty1 login screen and from there everything in Arch (including my now-upgraded DE) works normally. This error does not occur during all boots, but I cannot discern any pattern behind when I see it and when I do not. The OS X error and failure to boot occurs every time I try to boot into OS X.
I have learned a lot as an Arch user, but this problem is beyond me. Google has not been particularly friendly, understandably so given the peculiarity of the problem and my setup. I have not yet tried undoing the update I did on Sunday because (a) it would be a pain since there were >30 packages that were upgraded, and (b) I have no evidence that the upgrade was actually causative of this issue, though I may eventually attempt the downgrade out of desperation if I cannot find a solution. Note that the update I keep referencing did not including a kernel update.
I appreciate any advice or insight that you can offer.

I don't have much in the way of a solution for your problem, but to start with, what were the > 30 packages? In particular, was grub/refind updated (or anything else that would likely touch your efi partition? I know from my own messing with refind, that you can potentially 'damage' your partition layout with certain commands which maybe causing osx not to boot...
Then again, the errors may have nothing to do with your arch installation and maybe indicative of a different problem all together. Normal procedure is at this point is to backup your complete disk (clone/mirror it, read up on how to do that especially with regards to the encryption systems used), and try to diagnose for any problems the mbp maybe having.
You could use an apple rescue cd (that may no longer be available with newer mbp , I have no idea..) or maybe use a different harddisk and install osx there and see if you can get everything running 'normally' thus ruling out any funky errors with the hw. check apple's recovery options if need be.
I guess you'll just have to fiddle about a bit and try to more closely determine what the actual problem is. and again, backup your stuff!

My Mac can't get passed gray screen, and I cannot boot from cd. Help!

Always crashing and rebooting when booting from my new win7-disc. Lenovo 3000 n200 0769-erg

I have a fully working Vista system on my n200, trying to boot from my new win7-disc, even tried to boot from usb but it's the same:
"Loading windows files" followed by "Starting windows" with the new win7-logo.. After that comes a fat cursor(guess the resolution is lower, like in "Rescue and recovery").
This cursor and a black screen is all I see for ~5 secs before it crashes. Same thing every time.
It might be Rescue and recovery that starts there and crashes. If that's the case, how do I remove it/fix it in a safe way? Or can i try something else first?
I am able to boot Linux from CD fyi..
Thankful for any help.
Regards

hi perp,
If you have tried installing Windows 7 in both AHCI/Compatible mode and the Windows 7 installer still crashes, can you try to run a diagnostic on the RAM/HDD (to make sure there's no hardware fault).
To run the diagnostics:
1. Download the the UBCD ISO
2. Burn the ISO using imgburn
3. Boot from the diagnostic cd and use MemTest86+ for the memory test and use Data Lifeguard (if you have a Western Digital HDD).
To burn the diagnostic softwre on a flashdrive, follow this guide.
If you get any errors, you will need to contact lenovo for service or you can DIY and replace the defective components.
Hope this helps

[Solved] Grub errors 18 and 22 when booting from SSD

Hello community,
recently I purchased an SSD drive and am now having trouble doing an Arch install on it. Before that a 2TB HDD was in use. After building in the SSD I partitioned it (msdos partition table) creating partitions for swap, / and /home. Then I copied the files from the old /home partition on the freshly created one and installed Arch on the new / partition. Here's the partition setup:
$ LANG=C sudo fdisk -l
Disk /dev/sda: 2000.4 GB, 2000398934016 bytes

/dev/sdb3 2048 51863551 25930752 83 Linux # new /
Partition table entries are not in disk order
The problem is: booting from the SSD fails as follows: On the first try to select some Grub entry I get an error 22 "No such partition.". On any further try I get error 18 "Selected cylinder exceeds maximum supported by bios".
What works is to boot up the new system from the Grub residing on the HDD. So the problem is just the new Grub install in the SSD's MBR. Also it's not a thing of Grub's configuration, since copying the working menu.lst from the HDD install and reinstalling grub via grub-install /dev/sdb gives the correct Grub entries but selecting them results in the same errors.
So currently I'm booting from the HDD and selecting the boot entry for the freshly installed SSD system there, which works fine. But of course I'd like the SSD to be able to boot without "help" on the part of the HDD.
I tried to activate AHCI in the Bios but it didn't make any difference. The SSD is a Crucial M4 128GB.
Thanks for any hints,
PhotonX

I created a /boot partition now:

/dev/sda8 577722368 3907028991 1664653312 83 Linux
Then installed Grub on this partition: "grub-install /dev/sdb4". Then placed the SSD on the first position in the Bios, booted but got the same errors in Grub. So it doesn't matter where exactly Grub is installed, if it's somewhere on the SSD, it fails...
edit: Concerning using UUIDs: I couldn't find any howto regarding Grub (legacy) configuration with UUID's. Could you point me to some example config?
edit2: I now put the SSD on the first place in the boot list and started PartedMagic. But fdisk still recognizes the SSD as sdb and the HDD as sda. I think, the sdX identifier can be changed only by plugging the SSD in the first SATA port and the HDD in the second (while now it is the other way around).
edit3: I tried to install Grub from the HDD installation on the SSD (executed "grub-install /dev/sdb4" from the HDD system) and found out that, though I created a /boot partition on the SSD, the Grub files installed directly on /dev/sdb are used. So I tried to install Grub from the HDD system onto /dev/sdb (executed "grub-install /dev/sdb" from the HDD system) and got error 22 even before Grub's boot list was shown. But maybe it's really a bad idea to install Grub on another drive than the system it belongs to is located.

Win 7 and Arch dual boot [SOLVED]

There are other help threads about this, but I didn't want to hijack somebody's elses thread. Sorry for the long post, I just want to provide as much detail as possible:
I am trying to use Grub (not Grub2) to dual boot between Arch Linux and Windows 7. I had this working before using Windows XP, but when I reinstalled Windows 7 over Windows XP, Grub would no longer boot Windows.
1. If I manually choose the hd containing Windows 7 to load first in my BIOS, Windows 7 boots no problem. If I manually choose the hd with Grub and Arch to load first in my BIOS, I get a Grub menu, which boots Arch, but not Windows 7. Ideally, I think, I would like to have the internal drive with Arch ranked first, then the internal drive with Windows second in my BIOS. At least, that's how I had been doing things before blowing away XP and installing Windows 7.
2. Here is the (abbreviated) output of sudo fdisk -l
Device Boot Start End Blocks Id System
/dev/sdb1 * 2048 206847 102400 7 HPFS/NTFS
/dev/sdb2 206848 169934847 84864000 7 HPFS/NTFS
/dev/sdb3 169935570 1953520064 891792247+ 83 Linux
Device Boot Start End Blocks Id System
/dev/sda1 * 63 1028159 514048+ 83 Linux
/dev/sda2 1028160 3084479 1028160 82 Linux swap / Solaris
/dev/sda3 3084480 44050229 20482875 83 Linux
/dev/sda4 44050230 488392064 222170917+ 83 Linux
3. From that, I can tell that Arch is installed on sda: sda1 = boot partition; sda2 = swap; sda3 = root partition; sda4 = home partition.
Windows 7 is installed on sdb: sdb1 = system reserved partition (created automatically by Windows 7 during install); sdb2 = Windows; sdb3 = separate ext3 partition
4. I am comfortable editing Grub menus. This is an excerpt of mine:
# (0) Arch Linux
title Arch Linux
root (hd0,0)
kernel /vmlinuz26 root=/dev/disk/by-uuid/blah-blah-blah ro
initrd /kernel26.img
# (2) Windows
title Windows 7
rootnoverify (hd1,0)
savedefault
makeactive
map (hd1) (hd0)
map (hd0) (hd1)
chainloader +1
5. The error I get is "error 15: file not found" If I change the line reading "rootnoverify" to "root", I get the same error plus the bit about "filesystem unknown, partition type 0x7" so I think I'm pointing at the right partition/drive. That is, I know that partition type 0x7 is an NTFS filesystem/Windows.
6. I messed around with the Grub entry for Windows. I modified the root line to read "rootnoverify (hd1,1)", but things still did not work. I wasn't sure if I needed to bypass the "system reserved" partition created by Windows, or not. I also flip-flopped the two map lines, so they read:
map (hd0) (hd1)
map (hd1) (hd0)
That did not work either. I tried these combinations together, but Windows still would not boot. Always the same error message: "filesystem unknown, partition type 0x7"
7. I think I have a mapping problem given that Arch boots fine and Windows boots fine from the BIOS. However, I'm not sure how to fix this. Any help would be appreciated.
Thanks,
Culley
Edit:
Okay, so I fixed things. I just removed a bunch of stuff from my Grub entry. Even though Windows is not on the same drive as Grub, it does not need the map sections like I thought. I also removed the savedefault and makeactive entries, not sure if that made a difference or not. My new grub entry looks like this
# (2) Windows
title Windows 7
rootnoverify (hd1,0)
chainloader +1

(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
[Boot Loader]
Timeout=30
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...

Syslinux, dual boot with win7

I successfully removed Grub and got syslinux installed. I "can" get both Arch and Win7 to boot, BUT Win7 always initially starts up in Recovery mode, so I cancel, reboot and it starts right up. However, now in order to boot arch, I have to run a live Cd to change the boot flags back to the proper partition because windows has stolen the boot flag. Thoughts?

How did you make dual boot work using syslinux? In this topic:"https://bbs.archlinux.org/viewtopic.php?id=168819" guys are telling me right now me that it can't be done.
Please respond.
@71GA: We already gave you LinuxChick's solution in your original thread (specifically ssyslinux.cfg was generated correctly and I had to correct the changes that you made to a correct file). The problem is that you've done something completely unrelated to the bootloader, so LinuxChick's solution won't work for you.
@LinuxChick: Could you please mark your thread [Solved]?

[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.

Can't seem to install GRUB (Triple boot OSX + WIN7 + Arch.)

Alright I've partitioned my drive into 3 using disk util sda1 default mac boot or whatever, sda2 main OSX, sda3 arch, sda4 win7.
I've installed win 7 already, and attempted to install arch... I think I've done it, but all the tutorials said to skip installing the boot loader and install it manually from the live cd.
So basically I booted the live cd again, and did this:
grub-install /dev/sda3
but I get this:
/dev/mapper/../dm-0 does not have any corresponding BIOS drive
However, my compter works , and rEFIt detects OSX and Win7...
I really want to be able to use Arch, I'd appreciate it greatly if anyone can help me to get grub to work/or ger Arch to somehow boot alongside the other 2 OSes.\
PS. My computer is a MacBook Pro 15" i7 from late 2011.
Thanks!!
EDIT: Could it be because sda3 is ext4?

Self Solved:
Do not reboot after install, install grub directly after exiting arch installation.

[Solved] Windows 7 and Arch Dual boot- unable to boot into Windows7

Had to reformat computer and reinstall windows and Arch on two separate hard drives (Dual boot) .
Windows 7 was the first install on SDA: (/dev/sda1 - system reserved 100mb, /dev/sda2 - 20gb)
Arch on SDB: (/dev/sdb1- boot 94mb, /dev/sdb2- swap, /dev/sdb3 - root, /dev/sdb4 - /home)
Installed grub2 on /dev/sda. now grub bootloader loads Arch fine. Also shows Windows 7 (on /dev/sda1).
But when chosen Windows 7, it does not load and loops back again to boot loader screen.
In BIOS i have set disk drive SDB as first boot option.
If i choose SDA as first boot option in BIOS, same scenario is repeated.
I have gone through mostly all the pages related to the topic but i can not co-relate the solution
to my exact situation due to limited knowledge.
Can somebody pls help me as to how to edit grub.cfg so as to point it to load windows 7?
the entry related to windows 7 reads as follows:-
quote
### BEGIN /etc/grub.d/30_os-prober ###
menuentry 'Windows 7 (loader) (on /dev/sda1)' --class windows --class os $menue$
insmod part_msdos
insmod ntfs
set root='hd0,msdos1'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint$
else
search --no-floppy --fs-uuid --set=root F010D97410D941F0
fi
chainloader +1
unquote
for Arch set root value is hd1,msdos1 and working fine.
Thanks and regards.

This is exactly why I have chosen to use windows MBR and syslinux

Question about the "Windows and Arch Dual Boot" wiki

I've been reading this wiki http://wiki.archlinux.org/index.php/Win … _Dual_Boot to get a better understanding of what I need to do to install Arch along side of my XP installation and there's one point that I don't understand. Here it is
It is important to note that there is a 1024 cylinder limit with some older BIOSs. This means that the BIOS cannot access things beyond the 1024th cylinder (about 8.5GB), so the /boot partition should be in the first 8.5GB (space before Windows partition).
How does one go about getting the /boot partition created during the installation of Arch to install in the first 8.5g? I have installed Arch in Virtualbox twice so far just so that I'm familiar with the procedure and I can't see anything in the installation where I can do this.
There's one other item that is not clear to me as I've seen conflicting information on it. If I do create a seperate "/boot" partition for Arch, do I need to make it "bootable"during the installation? At this point I don't think that I do.
My understanding of installing to be able to dual boot is that I only need to install Grub to "Sda" and of course edit the grub menu to add the information needed for XP. Is this enough?
Thanks for any help.

Yes, you install grub to sda (master boot record), and add the entry for Windows. In the step where you partition the harddrive, you can choose where to create it. Actually it may not be that much of a problem anymore, my boot is on the third partition, after ~15 GB. You can forget about the bootable flag when using grub, it does not care.

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