Dual Boot install Fails

During installation of Windows 10 (dual booting) on same SSD (main) Windows 7 Ultimate, Install fails at 58%, retry 59%, just hangs for hours. Process- created partition, run install ISO from working DVD copy, freezes at approx 58%- Getting files ready for
installation.
Any help would be appreciated.
Thanks

Did you use any download manager to install Windows 10 TP ISO file?
What software did you used to create Windows installer file from ISO?
Usually such a problems are due to issue with installation file is corrupted.

Dual boot - Installing Win 8 on a preinstalled Win 7

I just puchased a Toshiba Satellite C55-A5195 Windows 7 preinstalled. But I would like to dual boot it installing Windows
8. Can I do that without messing the whole system? I know that I have to create a partition to install Win 8.

Thanks for your feedback, but I don't think your issue is the same as the one I previously explained.
The UEFI/secure boot setting is a basic configuration affecting the way the PC boots, regardless of whether it is connected to a network or not.
By the way, in the meantime I've seen in a shop exactly the same PC model which I'm using, now sold with Win 8 pre-installed, and it was working with the UEFI enabled (= BIOS "legacy support" disabled).
Therefore, the configuration I'm interested in has to be feasible, one way or another...!

[SOLVED] Lenovo T530 UEFI Arch/Ubuntu Dual boot - Arch fails to boot.

Hi All,
I have installed Arch to my Lenovo T530 to dual boot with Ubuntu using UEFI and Grub.
After installation, Arch is presented to me as an option when my laptop fires up. However, if I select it, the loader goes to a purple screen and then hangs.
I have attached here the bootloader scripts for my Arch installation (not working), my Ubuntu installation (working) and the output from sudo lsblk -o name,mountpoint,label,size,uuid.
Please let me know if there is more useful information I can provide. (I have output from Bootinfoscript available but it is quite extensive).
I am hoping to find out if there is an easily fixable error in the booting scripts used by Grub. If not, I have seen the section on dual booting with Arch in the wiki. My worry is that if I resort to it, UEFI looks to be temperamental at best and I risk breaking my currently working Ubuntu installation.
Thanks and regards,
Simon

Change the UUID here. Where did that come from?
EDIT: curiously, if you DuckDuckGo search this exact UUID, it comes up a bunch of times and has caused people headaches before. If you fix that you should be okay. If anyone knows why this same exact UUID would incorrectly be created on multiple systems, I'd love to know. Seems like some kind of issue with dual/triple booting and OS-prober.
2nd EDIT: this UUID is in the default in grub.cfg. For some reason, it sometimes won't be replaced by grub-mkconfig... Maybe the user didn't run grub-mkconfig, but edited the file him or herself? simon_sjw?

How can I initiate dual boot install from a CMD window...?

Laptop hardware meets sys req for Win 10 and currently runs 8.1
Samsung RV-511-S01UK
i3 380M @ 2.53Ghz
6GB RAM
Discrete Nvidia 315M 1GB dedicated VRAM
Having first tried 10 inside a VM... and it looks ok.... time to try it on real hardware instead of the restricted emulation.
I'm attempting to clean install and create a DUAL_BOOT on prepared partition
ISO downloaded direct from the correct link (SHA-1 checked)
USB... or DVD... installer created with the MS installer tool.
ALL attempts to install by booting from either installer medium, trying builds 9926, 10041 and 10049 (64 and 32 bit), end before they start....... the process stops completely at the very first screen.... the logo screen.... the indicator dots beneath
the logo screen which appear as standard to 'indicate' that a 'process' is happening in the background NEVER appear... even after an 8 hour wait in one instance.
Even if I follow the install instructions supplied on the download page here instead of booting direct:
5. Double-tap or double-click setup.exe from the installation media, and then follow the steps.
it gets to a point within the process and has to restart.... then it stops as soon as the logo screen appears just as it does when I try and boot from the created installers.
There seems to be a problem at the Windows logo screen which halts the entire installation process !!! It suggests a BIOS/Win 10 conflict, but only one way to really find out..... process log...?
The only way to discover where the error lies is to observe the process happening as it happens in real time (if that's possible) or create log file of my attempt.... from within a CMD window...? Unfortunately I don't know the language of CMD code
well enough.
I would like someone to assist with the correct code on how to initiate the install from within a CMD window so that I can see the process happen in real time within the window and therefore observe exactly where the instruction is failing.... but
as stated if running a CMD during install is not possible then a saved log file to refer to after fail and reboot into 8.1
This should make it easier to define the problem and as such discover the solution
If someone can supply the code it would be very helpful..... if no-one here knows I'll pop over to the Linux forum and ask one of the people there after setting up Ubuntu with a spare partition for the Win 10 TP
cheers

Hi base1268,
Can you find the following log files when you reboot into Windows 8.1?
C:\$WINDOWS.~BT\Sources\Panther\setupact.log
C:\$WINDOWS.~BT\Sources\Panther\setuperr.log
C:\$Windows.~BT\Sources\Rollback\setupact.log
Actually, for current situation, I suggest you use native boot to try Windows 10 Technical Preview：
http://blogs.technet.com/b/haroldwong/archive/2012/08/18/how-to-create-windows-8-vhd-for-boot-to-vhd-using-simple-easy-to-follow-steps.aspx
it still works for Windows 10 Technical Preview.

Dual Boot : Installing Windows XP on a Power Mac G5?

I am trying to figure out if it is possible to install Windows XP on a Power Mac G5? There are several Massive Multiplayer games that are only available for Windows/PC users. I need to have access to OSX also it is what I use for everything else. I saw Boot Camp -but it is only available for Intel Macs. It seems like there should be a way to partition the hard drive and upon startup to be able to select the disk I want to start up on. I did add a 500 GB internal drive that I can use as a second hard drive. [So I have two : one is a 180 and the other is a 500.] If I install Windows on one side of the 500 GB hard drive I am afraid I wouldn't be able to switch back to OSX.? Anyway I love Macs and I am not interested or able to buy a PC and I don't have the money to buy a new mac or Virtual PC software.? Any suggestions would be awesome?

VPC's CPU emulation speed depends on the speed of the Mac CPU being used. That being said, on my G5 Quad @ 2.5GHz, VPC reports a 533 MHz "686" CPU. Video memory is limited to 16 MB.
I have not seen performance to be anywhere near as bad as you've experienced. It's definitely laggy, but any delays are at most a few seconds. I have all the WinXP eye candy disabled to speed up the interface as much as possible.
In any event, the OP won't be able to use it for games as it lacks 3D acceleration (even if it were otherwise fast enough). I had tried to run the original Grand Theft Auto game (2D), but even that was too slow to be playable let alone a modern game. GTA 2 refused to run due to the aformentioned lack of a 3D accelerator card.
MS will no longer be producing VPC now that all Macs are Intel-based. There's really no more market for it now.

Dual boot, installing arch before xp

Hi! I'm just wondering, how I can enable dualboot. I've heard that there is a way to enable dualboot even though I've installed archlinux before I installed xp. But now I cant choose whether I would like to use arch or xp. Any suggestions on how, or even an guide to enable dualboot?:P

well, if u have problem and for those who wonder what zenlord said...
boot to arch linux install CD.
when it loads and gives u a set of instructions. U wanna boot with this parameter.
root=/dev/sdxx
where xx is the partion of arch install. This will load the kernel from arch install CD and mount the file system on your HD. Once it loads u will have a CLI, login and then issue the command
grub-install /dev/sdx
x = the HD MBR u would want grub to be installed too.
then edit /boot/grub/menu.lst as u see fit to get windows working.

[SOLVED] Advice for Arch install with rEFInd dual boot Lenovo laptop?

I am trying to plan an Arch install on a new laptop for dual boot with Windows 8.1, but I know there is a potential to cause huge problems so I have been trying to read and learn about the hard disk partition structure and how I might install the rEFInd boot files so that I am still able to boot Windows once Arch is installed. (Unfortunately for some tasks such as updating the maps on my satnav box Windows is essential). However I am really quite unsure if I am doing the right thing in the way I am thinking about the Arch install so I would appreciate any help from experts on the forum.
The laptop is a Lenovo IdeaPad Y510p which came with Windows 8 pre-installed, with the option to upgrade to Windows 8.1. The upgrade was completed without issue and I then looked into the question of hard drive partitions and boot. I had read posts on the Ubuntu forums about users who had installed Ubuntu on this same laptop and ended up being unable to boot Windows afterwards so I wanted to tread very carefully before executing anything which might cause really major damage. I had also read on the Lenovo forums replies about people who had replaced the hard drive and installed linux only to find that they could not boot to the recovery partitions, with replies from Lenovo moderators saying that if the partition structure had been changed then the laptop would have to be sent back to Lenovo for a factory repair.
On this laptop to get into the bios or boot options you do not just press the power button and hit an F key, but instead there is a special small "OneKey Recovery" button next to the power jack, which opens up with options for BIOS setup and boot options as well as normal boot or recovery. This OneKey Recovery button is therefore needed to boot a usbkey - the power button only allows it to boot to windows presumably until/unless a different bootloader and NVRAM entry is amended.
I have done all the initial ( safe!)changes necessary to move to the point at which I can execute the Arch install. From within Windows (switched off fastboot, and shrunk the "C:" drive to make space for linux partitions). I have also switched off Secure Boot from the BIOS, and made sure that Windows still boots up fine.
The current arch install iso (February 2014) boots under uefi just fine - and of course once booted I have access to the gdisk programme. That certainly showed the pre-existing partitions on the drive (8 partitions with partition number 2 being the EFI partition, and three recovery partitions!) with a GPT partition table, and it should therefore be possible to make the necessary new linux partitions in the now unallocated space on the disk that was freed up with the internal disk management facility within Windows 8.1. So at that point I created three partitions for a root partition (type 8300), a swap partition (type 8200) and another type 8300 partition which will become /opt in the installed Arch system.
In order to try and not make any changes to the partition structure I let the three new linux partitions be number 9, 10 and 11.
I am told that for a GPT disk it is a definite no-no to try to create more than one EFI partition. So I will need to use the existing EFI partition to place the rEFInd files and the kernel once I install Arch.
In this (Y510p) laptop the EFI partition contains the following structure:
BOOT/ - containing only boot.sdi
BOOTSECT.BAK
EFI/ which contains two directories Boot/ and Microsoft/
so EFI/Boot/ contains only Boot64.efi which is likely a fallback copy of the Windows 8.1 bootloader
and EFI/Microsoft/ contains a Boot/ directory - so
EFI/Microsoft/Boot/ contains loads of language specific directories like en-GB/
plus bootmgfw.efi (which I believe is the Windows main efi loader file)
bootmgr.efi
memtest.efi
The scheme that I am planning to use which I have previously used in pure Arch uefi machines, is that /boot is a directory in the root partition, /. That way /boot is an ext4 directory and will contain the kernel and initramfs plus the rEFInd linux config file.
Then I can mount the EFI (vfat) partition as /boot/efi and so I can then make a /boot partition under /. Then the EFI /BOOT/ directory would be seen in Linux as /boot/efi/BOOT/ and the Windows efi stuff would be in /boot/efi/EFI/Boot/Microsoft/Boot/ in which case I would presume that I have to make a new directory in /boot/efi/EFI/refind/ and put the refind stuff including the filesystem drivers there, and let the kernel go into the (ext4) /boot/ directory which would be preferred! However I am not 100% confident that this is what will work and I need to read more before trying to do the install. The thing that concerns me is how the system will handle the uefi boot process, and whether it would auto-detect the Windows efi file as well as the Arch refind efi file once the system has started up?
... and then there is the issue of the NVRAM entries and I am no longer confident that if I use the usual tools to create an entry (efiboomgr or bcfg), that I will get a successful dual boot system!
There is still a chance that I would irrevocably damage being able to boot to the Windows and Recovery partition boot options by messing up the EFI and/or the NVRAM so I have to tread very very carefully with this.
If anyone has gone through this kind of dual boot install with a Windows 8 or 8.1 machine using rEFInd for the bootloader, and can offer advice or help here I would very much appreciate it. I have another pure Arch system which uses rEFInd that works extremely well, but it seems that dual boot with uefi is a rather more complex animal than a pure linux system!

When there is an update to the rEFInd package you need to copy the files across to your ESP from the files contained in /usr/share/refind/ usually you need to copy the refind_x64.efi binary as well as the icons, fonts, and drivers directories. Since there is flexibility in how you configure the kernel and initrd files in terms of where they are located whether you need to do anything else when a new kernel update arrives depends on how you set your system up. If you have the /boot directory as your ESP partition which will then have the kernel and initrd files updated by default then there no need to do anything else when there is a kernel update. If the ESP is then at /boot/EFI and within that is your refind/ directory then that is where the replacement files go if refind-efi gets a pacman update. So it is actually fairly straight forward. If you configure rEFInd to look for kernels in some other directory than /boot/ then you may need to copy the files there after a kernel update but there is more information in the arch wiki about this.
During a refind-efi package update there are helpful files in the pacman output (and log) reminding you of what you need to do. eg for the latest refind-efi update you get:

By the way you can also boot uefi using grub and in fact you can get rEFInd to chainload grub as a backup bootloader as an added safety factor and have both rEFInd as well as grub installed simultaneously. How that can be done is explained in the thread at https://bbs.archlinux.org/viewtopic.php?id=181906

HP Notebook 250 64 bit Windows 7+ Ubuntu Dual Boot - Not starting!

Hello,
I have dual boot installed on the above mentioned laptop. While working, I was prompted to update flashplayer. Once the update was complete, the computer restarted and the usual dual boot menu did not appear. The machine keeps attempting to load it, fails then reverts back to shutting down and starting again. I ran diagnostic and the machine passed both hard drive and memory tests.
I have UEFI on the machine and have therefore tried to look for solutions here:
http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c01442956#N150
nothing applies since I don't get any error messages. Nevertheless, I tried a system reset, which did nothing.
This is some of what my system information outputs:
Notebook Model: HP 250 G1 Notebook PC
Product Number: H6Q66EA#ABU
Serial Number: [edited]
System Board id: 1854

How to implement a dual booting PXI system using windows 7 and labview RT

Good Day
My name is Mariano Ocana from the University of Manitoba, and I want to implement a dual system using windows 7 and labview RT in a PXIe-1082 chassis with a PXIe-8102 embedded controlled (the chassis came with windows 7 installed). What are the steps to use both systems (windows and RT) in the same chassis?, in the NI help comes an example implementing a dual system using windows xp and RT, it is the same procedure?.
Thank you in advance for all your help.
Regards
M. Ocana

Greetings, Mariano.
The real issue you have to contend with is whether or not you have a LabVIEW RT license. If the 8102 controller was purchased Windows-Only, you likely do not have a license to run LabVIEW RT on the controller - you can purchase one, I think it's about $500, and at that point you can request a LabVIEW RT Configuration CD (that's not what it's called, but the sales guy will know what I'm talking about). The Config CD is a CD that will partition your controller correctly with both FAT32 and NTFS filesystems (in the appropriate way) to allow you to run Windows 7 and LabVIEW Real-Time on the controller correctly. Once done, you can then switch within the BIOS between LabVIEW Real-Time and Windows in order to dual-boot.
Either way, you likely need to contact NI sales to either purchase an RT license (if one was not received at the time of purchase) or to request a Configuration CD (it might also be called a dual-boot install CD or similar).

How to set time in Dual-boot config with Windows 8.1

Hi,
I have been trying to workaround this problem i am having with Arch linux and Windows 8.1 time settings.
According to Installation guide on Wiki I set hardware clock to UTC and added my local time zone too.
But my Windows 8.1 uses hardware clock a local time and it is really confusing me.
I did tried to setup Windows 8.1 to use UTC (http://superuser.com/questions/494432/f … bios-clock)
but that settings is not working on my side (most Windows 8.1 users are also getting the same problem)
Please help.

I have two laptops which are dual booted arch and Windows 8.1. For both of those machines I set the Windows clock to be UTC instead of local using the method in https://wiki.archlinux.org/index.php/Ti … in_Windows (i.e. creating the .reg file and executing it - take care that the .reg file is created correctly with the .reg extension or it won't execute). I still allow Windows 8.1 to update its time from the network and it does not cause a problem, though the advice is to let Arch do the time synchronisation. (That may be because it is not yet summertime so I will also disable time sync in Windows before the change to summertime at the end of this month). I also followed the normal install advice for Arch and have the hardware clock in UTC, and have chrony set up to keep time in sync. Additionally I use KDE and have my normal timezone with DST adjustments for summertime. I have not had any problem with that way of working on either of my two machines.
I presume that if the Windows clock registry hack is done after the dual boot install it should not matter but I made that change before installing Arch.

Family Pack Leopard install fails G4 Dual 1.2Ghz

All, I purchased the Leopard family pack and have successfully installed it on an Intel Macbook Pro and a G5 2.3Ghz DP machine - flawless, no problems during installation or after.
However, any attempt to install on a G4 Dual 1.2Ghz + 2Gb of RAM + just bought a Seagate 500Gb Barracuda internal drive (well within the designated technical requirements), I've tried the following.
1. Booting the G4 off the Leopard install DVD, I get the following error: Failed Install message = "The Installer could not validate the contents of the Essentials Package...".
I can never get beyond this point. After receiving this error, the internal disk isn't even recognized on the bus - I have to pull the disk out, put it in an external case to reformat it. I've even tried a low level format and also had Seagate replace the disk thinking it was defective.
2. I then thought it may be an issue with putting the Seagate disk in cable select mode versus master / slave configuration. The Seagate is the only hard drive in the machine. I have tried both cable select and master/slave configuration - both freeze after install, etc. without fail.
3. Tried installing Leopard on the G4 by connecting it to the G5 in target disk mode. It installed, but routinely just freezes (NEVER had this issue with Tiger on this machine).
I do see lots of people posting issues with the "The Installer could not validate the contents of the Essentials Package..." error.
For the record, after successful Leopard install using technique #1 and #3 - I am also unable to run the Migration assistant - it fails every time with a kernel panic. I'm not having any trouble with the Leopard install media on any of the other 2 machines, nor did I have issues running the migration assistant.
Any ideas are appreciated. thx,

themdg - you said you put back your 2-512 original RAM cards and tried to install Leopard and the install failed. But my original, factory-installed RAM was third-party RAM which prevented me from installing Leopard, giving the “essentials” error. Only when I purchased RAM from Apple, and used only that RAM to install, could I get it to work correctly.
Check your original RAM. If it is not the Apple brand, it may not work because of that, even if it was the factory-installed RAM.
After I installed Leopard with only the Apple RAM, I added back the third-party RAM and I’ve been running Leopard flawlessly since.
It seems the installation software, which meticulously checks the installer disk for flaws, should also check the RAM to see if the installation will be successful (i.e., check to see if it is going to produce the “essentials” error) and also check to see if you have enough valid RAM to install, before it begins installation, and to let the user know there will be a problem unless the RAM is changed to valid cards.
I “assumed” I had enough valid RAM when I first tried to install Leopard because I had a G5, but it had only 256 MB of non-Apple brand RAM (minimum of 512 is required). A direct check of that by the installer and letting me know it was a problem would have saved me a lot of trouble checking lots of other potential problems, like a bad installer disk, a third-party drive, etc., before I figured out it was insufficient and incompatible RAM for the installation.
I read the minimal requirements for installation of Leopard and probably someone will say I should have checked all those before I tried the installation, but I didn’t, as I’m sure many others have not, because we “assume” Apple had tested it and would prevent us from making any mistake like this.
Previously Apple made their software and hardware to “just work” by providing error messages before we made an error and we have come to rely on that. But they overlooked this problem on this update. It’s the first time I’ve had a problem with an update from Apple.
I’m still a loyal Apple user, but I’ll check requirements a little closer with future updates.

Dual booting pre-installed Windows 8 and Linux?

I just bought a G780 with Windows 8 pre-installed. Ideally, I would also like to install some flavor of Linux. I've been searching but not finding much info on how difficult or time-consuming this would be, or if there are any special considerations or anything. I've found some guides on dual-booting Windows 8 and Linux but they were all for installing Windows straight from a disk, not anything where it's already pre-installed, and some indicated they thought it might be problematic to use a pre-installed version of Windows. Anyway I was hoping that if anybody has done this on the G780 or even a similar laptop that you could share how it went and any difficulties you encountered. I'm open to using any Linux distro if it'll be easy to install. I would appreciate any info you could share. Thanks.

I had issues with Windows 8 as pre-installed on my G580, my employer at the time was using Windows 7 only and would not allow upgrades for security purposes. I deleted the entire drive (including hidden) knowing at some point I would re-install Windows 8 or later from retail disk when needed.
Linux can resize partitions during the install process, but be careful not to disturb the hidden partition or the windows boot loader in the process. Linux Mint is the best yet for this purpose, OpenSUSE and Fedora failed, CentOS failed and Ubuntu was not able to boot, but did not "hurt" the windows partitions.
Good luck.

Mac mini with 10.6 installed - dual boot 10.8?

Hi all
I have an a Mac mini with 10.6.8 installed (think it came with 10.5) and would like to buy Mountain Lion from the Apple Store and install it as a dual boot setup. I think the hardware is too old for 10.10 (although it does give me the option to download it from the App store). I would like to keep my existing install and install 10.8 either alongside 10.6 or on a separate partition. Couple of questions;
Can I shrink the partition that contains my existing 10.6 install (there is plenty of space on the disk), create another partition and install 10.8 onto it?
Failing that can I install 10.8 alongside 10.6 on the same partition (like we used to do for OS9 and OSX)?
For 10.8 I will be receiving a "content code" for the Mac App Store - once I download the files and start the install presumably the Mac will restart and I will get access to the usual install utilities (without the OS running)?
Many thanks for any help.

If your computer will run Mountain Lion, it will run Yosemite.
1. Yes.
2. I would go with 2 partitions.
Yes.
Check that your computer is compatible with Mountain Lion/Mavericks/Yosemite.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
Mac mini (Early 2009 or newer) model number 3,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
8 GB or more of available space
Check to make sure your applications are compatible. PowerPC applications are no longer supported after 10.6.
Application Compatibility
Applications Compatibility (2)
Do a backup before installing.

Failed Dual Boot Installation

I tried to install Linux (Stormy) on to my external hard drive to dual boot for engineering/programming purposes. I did not delete or write over anything on my hard drive, it was all installed onto the external. The Linux installation failed and now the computer won't boot OSX at all. I tried to put the installation disk in (for the utilities, not to write over all my stuff) and it finds the hard drive, but it won't let me look at it or do anything with it. I would really like to be able to either restore to what I had before the failed installation or just get back my documents and pictures even if I have to reinstall most of my programs. What do I need to do?
Macbook Pro Mac OS X (10.4) Not 100% sure on the OS version as I can't boot it to check

Did you use bootcamp? If so unless you specifically chose to install Linux on the internal drive, your OS X installation should be completely safe. Also when you say Linux installation failed - when and where exactly? What was the error message if any? (Like during Bootloader install for example?)
Can you post a screen shot of what the Disk Utility says about both your drives (internal and external)? That way we will be able to tell if you (by mistake) installed Linux on your internal drive and/or what the partition map looks like on the internal drive.
