Problem in dual boot xp & windows 7--Lenovo g450

I installed Windows 7 & xp and i set up dual boot menu also. The problem is Windows 7 works only with ACHI HDD configuration in BIOS and XP works only with IDE HDD configuration in BIOS. So eyery time i boot other os, i have to set HDD configuration in BIOS. Is there any solution to avoid the BIOS settings change?

Put the HDD to IDE. Install XP, Leave it IDE install Win7 and they both will dual boot. Thats what I used to triple boot.

Problem with dual boot after upgrade to Mountain lion

Hello Every One,
I have a Macbook pro from 2009 which had dual boot option Windows 7 + Snow Leopard.
The windows 7 had 2 partitions (C; and D: an extended partition).
I upgraded the OS X to Mountain lion. after upgrade the system showed 3 options at boot time. Mac, Windows and a recovery partition.
when i boot to windows the D: drive is gone...I mean even though i can see the partition in partition software, windows 7 stopped showing D: in "My computer".
So i used testdisk utility to get the D: drive back and now when i boot to mountain Lion i am able to access both C:(BOOTCAMP) and D: drives.
but now the problem is during boot time my Mac Book pro doesn't show the windows option.
Can some suggest a means to boot into windows 7? Also what is the purpose of recovery partition that Mountain lion adds to the system? I mean is it going to hurt if i get rid of it so that i can go back to my old configuration of 3 primary partitions (1 for windows 7 ...C: bootcamp + MountainLion) + 1 extended partition for D:
any help would be appreciated?
Regards

When dual-booting with Windows 7, Mac OSX time settings reset every reboot.

I have recently installed Windows 7 Professional on my mid 2010 MacBook Pro via BootCamp (Running Mavericks BTW). Everything runs grean and have not experienced any problems on the Windows side, but I have a problem with Mac OSX now. When I am using Windows 7, and I reboot into Mac OSX, I find that my time settings are wrong. It seems like my time zone has changed, because the date is correct, as well as the minutes, but the hour is always wrong. When I go to Date & Time in System Preferences, and my time zone is correct, but I still have to chage the hour in the time. Any ideas as to why this is happening and how to stop it would be greatly appreciated.

If you dual boot your Windows PC with OS X or Linux, you may have experienced a problem in which your clocks reset themselves incorrectly every time you boot into Windows. Here's a simple registry edit to fix that.
Essentially, the incorrect clock setting happens because OS X and Linux use GMT time while Windows tries to synchronize with your local time zone, getting confused when you reboot between the two. Apple's own Boot Camp drivers for Windows are supposed to fix this problem, though some users have noticed that it still happens even with the drivers installed, and some Linux users are left out in the cold. Furthermore, if you have a Hackintosh, you can't install the Boot Camp drivers, so you'll need to find another way around the problem.
To fix it, just hit Start and type regedit.exe in the search box. Hit Enter and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation. Right click anywhere in the right pane and hit New > DWORD (32-bit) Value. Name it RealTimeIsUniversal, then double click on it and give it a value of 1.
Lastly, reboot into OS X, then reboot back into Windows. You should now notice that your clock actually displays the correct time.

Arch does not show up in Grub when dual booting with windows 8

I just installed Arch linux, dual booting with windows 8 using the beginners guide[https://wiki.archlinux.org/index.php/Beginners'_Guide] itself. Now Grub is installed and i can only find Windows 8 and I cannot find Arch. Is there a way I can find if arch linux has been installed and show up in Grub.
Sorry, I am a newbie, but i chose to post this topic here and not newbie corner as it is installation related.
My windows 8 is installed on /dev/sda1 with ntfs partition type. Arch Linux is installed on /dev/sda6 and it is ext4 partition. I dont know if this info helps. I am using Thinkpad R61

I am sorry, yes you are too late. I have wiped windows 8 and performed clean install. No regrets. And as a matter of fact, I did grub-config and then installed os-prober. That could be the problem. Thanks. I will try this again another time.

[SOLVED] RTC and dual booting with Windows 8/8.1

I am planning ahead of installing Arch on a windows 8.1 laptop, and need to understand whether or not the known Windows registry hack to get windows to use UTC for the RTC is still valid for Windows 8/8.1? I have been searching via google and the usual sources of information, but it is not clear to me if there are problems doing this, specifically if arch is dual booted with Windows 8/8.1 rather than older versions of the MS OS. Certainly I have used the technique without any problem in the past when dual booting Windows XP with Arch on several different machines.
Does anyone have personal experience with doing this on a Windows 8 or 8.1 machine and can report here on whether it works successfully or not?
Thanks for any advice.

Since there were no replies at this point I thought I would just go ahead and implement the registry hack on the Windows 8.1 O/S in the laptop and see if Windows behaves. It appears to be OK, with the displayed time being correct after reboot, and time synchronisation remaining fine with no problems seen in the displayed time, although I won't be able to read the RTC directly until I have completed the Arch install in the coming week or two. I now don't foresee any issues with the time synchronisation between booting Arch and Windows 8.1 so I will mark this as solved.
Since the RTC is now in UTC then normal clock config in Arch using chrony should perform normally once the install is done and the new system set up.

Windows has a software updater built into Windows and when you install the Boot Camp drivers then it will install an Apple software updater also. I believe Windows is set to automatically download and install your updates as does the Apple software Updater. They both will update the individual files it needs to periodically.
"Microsoft updates" and "Windows updates" are basically the same thing in Windows. Are you talking about the "Windows support software" when downloading from Boot Camp Assistant? Apple installs a software updater for it's Boot Camp drivers in Windows 7 so you can do it manually or automatically.
The "Hot Fix" your referring to is only for certain motherboards built from other Windows only computer manufacturers and does NOT pertain to any Apple computers.
If you have a problem with your computer then it's best to ask a specific question so we can help better.

Separately encrypt dual-boot system: Windows+Arch

Hey guys, I want to use a dual-boot system: Windows 7 + Arch (windows being first on hdd). I would also want to encrypt them, but make it so I could access them with different passwords, like if I enter arch, i woudn't be able to see contents of windows, and vice-versa. I need arch to be on LVM, ext4 filesystem(the latter not so important, if it's trouble).
I've come accross this guide: https://aprescott.com/posts/dual-bootin … encryption which describes windows 7 encrypted with truecrypt + arch(on lvm) encrypted with dm-crypt+luks, grub legacy is put inside MBR, truecrypt bootloader resides on linux /boot, copied from MBR after truecrypt installed it there and then replaced with GRUB. With described approach there is windows boot partition and linux boot partition which remain unencrypted.
1) The question is, is it possible to do something similar but make those boot partitions encrypted too? so the only thing unencrypted would be MBR? I've read that people used Disc cryptor and with it easily encrypted windows boot partition with no trouble. What about linux boot partition? Maybe there is a way not to make separate /boot for linux, and encrypt the whole lvm partition with truecrypt(so truecrypt would install it's bootloader into MBR and i could save it and use just like in the link i gave above)?
2)Another question is for people using truecrypt for whole disk encryption. When you do full disk encryption or system encryption(for example Windows), the only thing left unencrypted is MBR? Is the boot sector of windows partition encrypted too? So in this case it maybe possible to keep MBR(at least the bootloader, without partition table) on separate media.
3)Also, in case of full disk encryption, is partition table encrypted too?
and please, I don't want questions as "Why do you need it this way?". I just want to have full disk encryption, so if the MBR is the only thing unencrypted I could keep it on separate media and boot from it(Disc Cryptor allows such feature), but I also need the system to be split into windows and linux parts, accessible by different passwords. And I dont think the idea of using truecrypt hidden partition and hidden os is good in here.
Thanks in advance.

3)Also, in case of full disk encryption, is partition table encrypted too?
Take a look at diagram #1 . Mbr and partition table will be not encrypted. You don't want that: there are no sensitive data in there; both windows and linux need to access partition table to know where are partitions on disk; mbr must contain some not encrypted code that will be loaded by bios, since that code can't be encrypted it can be modified (potentially in such a way to hide the modifications from the system), as long as you boot from this device there is no way around it without "secure boot" and mbr singing.
I believe windows boot partition and windows partition can be encrypted with truecrypt (you need to check that, I don't know truecrypt). There still will be some minimal not encrypted bootloader in order to ask you for for key / passphrase, so it is not 100% secure (someone could replace it; search for "evil maid" attack by Joanna Rutkowska).
Linux bootloader (I forgot about it on diagram) and linux boot partition can't be encrypted (again, unless you do: truecrypt -> grub2 / syslinux -> linux, and there still will be not encrypted minimal bootloader).
You see, the problem is always the same: you can't boot from encrypted device. You need something that will decrypt it first.
I just want to have full disk encryption, so if the MBR is the only thing unencrypted I could keep it on separate media and boot from it(Disc Cryptor allows such feature), but I also need the system to be split into windows and linux parts, accessible by different passwords.
In order to secure boot partitions / bootloaders one could separate encryption and bootloaders, keep data on encrypted disk and keep bootloaders code at secure location (i.e. on pen drive attached to key chain). Take a look at diagram #2:
/dev/sda /dev/usb-stick
+--------------------------------------+ +--------------------------+
|(mbr and partitions table) | |(mbr and partitions table)|
| +----------------------------------+ | | +----------------------+ |
| |other data / partitions | | | |linux boot partition | |
| +----------------------------------+ | | | +------------------+ | |

| | |home | | | | +----------------------+ |
| | |------------------------------| | | +--------------------------+
| | |swap | | |
| | +------------------------------+ | |
| +----------------------------------+ |
+--------------------------------------+
In this setup you boot your system from usb stick. Bios will load and execute mbr and bootloader from usb stick (and you know its good since you have it physically secured), it should decrypt luks and boot system. You still can run windows with truecrypt using /dev/sda as boot device. I know I didn't exactly answered your questions.
1)so this way i can leave mbr(including partition table) empty on hdd, while having them on usb stick? good. I can put copy of mbr with truecrypt loader on that usb stick too along with /boot partition just like in the link i gave above? So there would be NOTHING left unencrypted on my hdd? i like it.
2)My main goal is that hdd would look like blank if someone would want to check its contents. I've heard using Luks leaves some traces in the volume header?(it's not possible to use truecrypt for full linux system encryption too, right?)
3)How do i properly put /boot on usb stick? Also will there be any troubles updating arch with /boot being on separate media?
thanks!

yes you need the updates and patches.
Only some of the drivers that Windows will automatically install at times
and always make sure to insure it is using restore points
do all the maintenance andsuch as normal
use MS Security Essentials for AV is really top notch
Clean disk space
Use WinClone new program to inisure you have a restore image

I kept a dual boot of windows 7 and mac os x lion in macbook pro. so, should i keep antivirus for windows 7? which is prescribable between bit defender(bd) and microsoft security essentials(mse)?does bd and mse un-installs easily?

lower your font size unless you have difficulty
MS Security Essentials is excellent
Then again maybe time to investigate Windows 8 RP (which uses Defender)

Dual Boot with Windows ME

i am very new to all this stuff. Can someone please guide me on how to go about installing Unix so that it also dual boots with windows ME.
i am planning on doing some unix work..and installing oracle and learning oracle in the bargain at home. do u think this is the best way to go. any suggestions/guidance is appreciated.
many many thanks

I'd consider buying a second, inexpensive PC for Solaris. You can get a $20 mechanical switch that will let you share a single monitor. If two keyboards and mice are inconvenient, you can buy a KVM (keyboard-video-mouse) switch. If you just want to hack around, it's much more convenient to have two PCs. (IMHO)

[SOLVED] Dual boot with Windows 8, problems after updating Windows

Hi all,
I have been maintaining a dual boot of arch and Windows 8 for some time. I recently updated Windows to 8.1, and found that the update process had two side effects:
1) The update added a new partition in the middle of my file table, so my /etc/fstab which referenced "/dev/sda6" was wrong because that partition is now "/dev/sda7."
2) The default boot device was switched to the Windows Boot Loader instead of grub. But, this is not a problem because I can work around this by using the "Choose boot device" feature of my bios at start up.
So, neither of these problems are critical for me at the moment. I can fix my fstab and just press a hotkey at startup.
EDIT: I have avoided the /etc/fstab issue by referencing my partitions using UUID as specified in https://wiki.archlinux.org/index.php/Fstab.
How do I set the default boot device back to grub? There is some weirdness here, I think windows is using UEFI booting and my grub uses the old booting system.

Rex: I tried that command, got some warning messages regarding blocklists, but no dice.
Loqs: You are right about windows using a ESP and UEFI while my linux is not booting using UEFI. My bios is configured to try "Legacy boot" first before trying UEFI. Getting linux to boot using UEFI seemed like a pain, so...
I went into my BIOS settings and found that the Windows Boot Manager boot device was listed in front of my hard disk (which boots linux). I don't think this used to be the case, so something about the update caused my BIOS to reorder the boot devices (probably because the partitions changed).
Switching my hard disk to be above the Windows Boot Manager in the boot device list now makes me boot into linux by default, and I can boot into windows by pressing a hotkey at bootup and selecting the windows boot manager.

Trying to create dual boot with Windows 7 on Yoga 11s

I was trying to install Windows 2008 server (I said Windows 7 in the title because it's essentially the same) on a Yoga 11s in dual boot configuration with the factory-installed Windows 8 upgraded to 8.1, and as expected it's a pain in the butt.
I ran into the catch-22 that you can only boot from a USB external optical drive in legacy mode, and then Windows refuses to install on a GPT-type partition. Dead end there.
As plan B, I tried installing from my MSDN DVD from within Windows 8.1. It chugged along for a while, but then hung after the second restart. It reached a state where the machine is dual boot, and goes into Windows 8.1 OK, but 2008 server hangs on startup even in safe mode. Probably it's a driver problem. I downloaded all Windows 7 drivers for the Yoga 11s from the Lenovo website, and they would work fine for 2008 server if there was a way to put them in place.
I have been through the process twice before on previous machines. After getting the server OS to install, none of the devices work well or at all, but I could patiently install the drivers using device manager. This is the first time where I can't get the server OS to install to a bootable condition. Is it hopless, or might there be documentation somewhere about how I could manually place drivers in the right folders to enable the OS to start?
Plan C might be to follow Lenovo's instructions to create a UEFI bootable USB flash drive and try to install from that. Would that work better than installing from within Windows 8.1, or just reach the same roadblock?

Reformat that new drive with SL DVD.
Go into SL DVD again, go to Utility Menu and choose DU.
Then try repairing the drive or better yet, just erase the drive (not the volume) and try again.
There are enough changes between Tiger partition scheme and SL that you would want to. RAID arrays built with Leopard will not allow installing SL, they have to be recreated (and can then have Leopard and SL).

SYSTEM RECOVERY (F11) is inaccessible after dual-booting Windows 7 and Windows 8.

I dual booted Windows 8 with Windows 7 and now the RECOVERY partition (F is not loading upon pressing F11. It gives me the boot configuration data error. I have it marked as Healthy (Primary Partition) and I am able to access the files via. My Computer in both OS, but not through F11 System Recovery.
The bcdedit log is here: http://pastebin.com/b0Y5Hd1F
My partition letters:
C: Windows 7
D: Windows 8
F: RECOVERY
H: SYSTEM
In Visual BCD, One WRE is set to D: and the other is set to F:. Should i set both to F, which is the actual RECOVERY partition?
[2] The UEFI boot setup is unable to create HP_TOOLS parition because 4 partitions already exist. I don't remember having the SYSTEM partition earlier so maybe that repalced HP_TOOLS?
[3] When I try to create a recovey media, the orange circle filter keeps of going even after I have inserted the an external USB hard drive for it to detect. Does it usually take this long? I am guessing once the recovery media is made I could do system repair from there and get RECOVERY to work?

What is the p/n? Remove the battery and look for it. Post all alphanumeric characters.
CTO means configure to order. That means only you and HP know the notebook's configuration.
The problem you are going to run into is that there is a maximum of four primary partitions allowed by Windows. That is by design. It appears that you removed the HP_TOOLS partition, which was a requisite for the UEFI diagnostics.
Frankly it looks like what you will have to do is put the UEFI environment on a USB stick.
I would create the recovery media on a high quality 16GB USB drive.
The partition schema must be as follows:
1) C: (NTFS)
2) HP_Tools F: (must be FAT32)
3) RECOVERY D: (NTFS)
4) SYSTEM (NTFS) created by the Windows install process
I am not aware of a dual-boot or more schema that allows a UEFI environment with the Recovery Manager accessible from F11. I wish I had better news for you. Perhaps our forum Provost DavidPK knows how it can be done.
I do recommend that you copy the RECOVERY partition to an external disk for safety sake.
If you are able to boot into the recovery manager I strongly suggest that you create your recovery media. If you do not do that you will not have a copy of your operating system and drivers for a plan B. I did not go with the option you used and did not create problems to deal with later.
When I play around with my loaner notebook and configure it to dual/triple boot, I always install a different hard disk and put the original one aside. You can still return your system to its original configuration and then take the hard disk out and use another one to play with. I believe that would be the wisest path to follow.

How to dual boot with Windows 8.1 and Arch?

Hello everyone,
I've been looking into using Linux as my daily driver since having some experience with it on a server. After some digging around, I think Arch Linux is the best distro for me, now onto where I am.
I'm currently running Windows 8.1 (updated from Windows 8, which updated from Windows 7) on a Dell Inspiron 15R SE laptop, I want to dual boot Arch Linux with it. I've looked at the wiki and I'm still not entirely sure what to do.
Can anyone give me a quick list of steps of what to do to dual boot this? I've dual booted Ubuntu in the past and it was really simple because an installer did it all.
Thanks, Expi.

I'm not entirely sure what I should be partitioning the C: into, I've done partitions before, just not for Arch and then I'm not sure whether to use GRUB or syslinux, or if I even need those. Or if I need to use GPT or MBR?
Your disk is already partitionned so you don’t have to choose between GPT or MBR, the choice is already made.
You don’t partition “C:”, that is the name of a Windows partition. You partition a drive.
Grub or syslinux, use whatever the beginners guide tells you to. Personally I think syslinux is simpler which is why I’m using it (but I’m not dual-booting, if that matters).
You’re not saying what your problem is with partitionning, so it’s hard to help.
Thanks for getting back to me, I'm not sure if I just create one large partition for Archlinux or if I have to create multiple? Where I'm also confused is with the Creating Filesystems part of the guide. I don't understand how I'd do this in Windows, or what /dev/sda1 is referring to.
As for the bootloader part, the Beginner's Guide gives you a choice between syslinux and grub, what I'm not sure about is which to use considering I'm dualbooting. How it will affect my windows bootloader, do I disregard that and use GRUB now? I'm unclear on how that works.
I'm also aware I need to disable Secure Boot, I just searched my BIOS options and couldn't find anything remotely relating to that, so I'm assuming it's not an issue since this computer was originally on Windows 7 anyway?
Thanks again, Expi.
