• Dual-boot-2 - MBR and GPT disks

  I built a PC with a dual-boot, with the disc has been formatted using MBR and the two OS is Vista and 7. A table is written to the MBR with pointers in the two BONES, with this visible table before the start, allowing me to choose one or the other. Well, it's logical.

  But what will happen in the following scenario? I have install Vista on an MBR disk, remove the disc, install a second disk MBR and install 7. Then I put on the first disc in the PC, attach SATA cables and press the power switch. What is going on? Do not I have a dual boot situation where pointers are not written, in other words, the dual-boot will exist only as long as both drives are connected? Or MBR a disk will have pointers to the two OS written in it, leading to the same situation to have two OS on one drive? And if the pointers are written on a drive, which makes the master, which drive is chosen and why? I guess that the chosen drive would be first in the sequence of port, for example, 0 before 1.

  And what will happen if the two drives had been formatted using GPT? Any difference?

  If you install Windows Vista on a disc (call it drive #1) and Windows 7 on another drive (disc 2) with deleted #1 disk then you will not have a dual boot system. You can choose which drive / OS you want / load (select a specific disc) in the BIOS menu when you turn on first of all of the computer. It is the same with TPG.

  If your drive is running out of space because two versions of Windows installed there is a way to move Windows 7 to another drive and do not have to perform a new installation.

• Convert dual boot in RT

  Hi all

  Does anyone know if it is possible to convert a dual-boot controller to RT only?  I have a hard drive that comes to die and to simplify things, I would like to install RT only on the new drive, as we move only has RT.  Ships (8110) controller PXI with software backup, but you need to install Windows and the RT operating system if you use.  Any thoughts are appreciated.

  Thanks, Matt

  Hi Matt,

  Sorry for the lack of clarity. Here are the steps to follow.

  1 controller boot RT safe. In the left pane in MAX, right-click on the target, then select "format the drive.

  2. after completion, restart the controller under LabVIEW RT. MAX, the target must appear in its default state without parameters or parameters defined by the user.

  3. expand the target in the left pane of MAX and right click on the item "software". The only option that appears is "Add/Remove software". By selecting this item will launch the Installation Wizard of the RT software, that will guide you in installing the necessary software on the target.

  I would like to know if you have any other questions and have a happy Thanksgiving!

• HP Envy Rove: Boot with MBR instead of EFI without removing the GPT partitions

  Hello

  I activated the Legacy Startup Mode in the Configuration of the UEFI and I would how I can give greater priority to the Legacy boot (boot MBR) vs the EFI Boot.

  I mean, how do I start using the MBR without destroying GPT partitions or files EFI?

  I don't have an option in the BIOS to select the 'priority '.

  Welcome to the HP Forums, it's a great place to get help, find answers and advice,
  Thanks for posting your request, I'll be more than happy to help you

  If I understand correctly you want to use the trunk legacy rather than the UEFI boot, before getting into the details, however,

  Here is the difference between Boot EFI and start-up of the legacy
  
  This is the process used by the firmware to find the target of starting:
  
  Legacy boot is used by the firmware BIOS boot process.
  The firmware keeps a list of installed storage devices can be bootable (Floppy Disk Drives, hard drives, optical drives, tape drives, etc.) and list them in a configurable priority. the POST procedure has finished, the firmware loads the first sector of each target of memory storage and it scans for a valid Master Boot Record (MBR). If a valid MBR is found, the firmware passes execution of code found in the MBR, bootloader that allows the user to select a partition to boot from. If we don't get, it proceeds to the following equipment in the boot order. If no MBR is found at all, the user is presented with the famous "Please insert system disk".
  
  UEFI boot is used by the UEFI firmware boot process.
  Firmware maintains a list of volumes of valid boot called EFI Service of Partitions. During the POST firmware procedure UEFI scans all bootable storage devices that are connected to the system for a valid GPT GUID Partition Table (). Unlike a MBR, a GPT does not contain a boot loader. The firmware itself scanning the closure for a score of Service EFI to boot from. If no boot EFI partition is found, the firmware can fall back on the boot of the legacy method. If boot UEFI and legacy boot fail, the famous "Insert system disk" will be presented.
  
  In general, the UEFI boot is more desirable.

  I already have a partition, but when I boot from disks, is not has the option to select a partition

  Thanks already

  > Satellite Pro L40 - how to make a dual boot with two recovery disks?
  Short answer: you can't do that. Maybe if you have two hard disks (I tried didn't) but as much as I know your SP L40 has only one.
  Ask this smart guy, how to do this. Maybe it's a useful tip.

• dual-boot apps and saving disk space

  I remember there was a trick to save disk space during dual-boot installation of applications on the same location on both operating systems, although it did not always work due to its location different %APPDATA%\microsoft\windows\sendto in Windows 9 X and XP. Was this something more to the other case pointing to the directory \program files on the C drive instead of the D drive? It's been a while since I used it and I think that I forgot something important. As the problem of recycling bin.

  In addition, at - it someone remind if one of the following conditions has had problems using the trick?

  Applications:
  Open Office 2.42 (latest version 98, I could just installing OO3 place)
  Office 97 (might install Office 2003 instead, I like it better and it can read the docx)
  WinRAR
  Printing 5.0 (version of Windows 95, will not install on Vista on my other machine, but works under virtualPC)

  Games:
  all games of the Infinity Engine (Baldur's Gate series) and Icewind Dale series
  Final Fantasy VII (FF7)
  Final Fantasy VIII (FF8)
  Pool of Radiance: ruins of Myth Dranor (reflection, with the issues surrounding this match, I don't try, I'll just boot 98)
  Starfleet Command
  Starfleet Command II:Empires at War
  Expansion of Starfleet Command II: Orion Pirates
  Fleet command (may not be not worth, the readme file has a lot of known issues with XP)

  You are right! That's the thing...

• Dual Boot with windows XP Pro with 2 HARD drive, error on secondary windows install: "Windows did not start because of a configuration of the disk of the computer problem. Could not read the selected boot disk. Check boot path and disk hardware... »

  Hi, I recently bought a new Hitachi 1 TB internal hard drive. I wanted to do a clean install on the new drive (d), be able to dual boot my computer and leave my old 300 GB disk (C :) as the primary windows installation. After physically installing the new HARD drive, I noticed that "new hardware found" and the the brand name flashed in the bottom right corner. I thought I'd see the new hard drive in my computer, but I did not. I initialized the new HARD drive with the computer management window (right click on my computer - manage) and I also formatted in NTFS (I had to change my printer hard drive letter to assign the new HARD drive with the letter D, but I've made other changes after this step). Now, I could see and use in my main windows on the C: installation. I then installed a windows new copy XP pro with the installation CD I got for my C: but on the D: (Note: I have a Dell computer (and the Dell reinstallation CD) and my current version of windows has SP3 while the installation CD is only SP2) (I also reformatted my HARD drive during the installation of windows to NTFS)

  Now when I try to start on installing the new on my D: I get "Windows did not start because of a configuration of the disk of the computer problem. Could not read the selected boot disk. Check startup disk and hardware access path. "and another line saying to refer to manuals HARD drive and windows.

  My Boot.ini file at this time was:

  [boot loader]
  Timeout = 5
  default = multi (0) disk (0) rdisk (0) partition (2) \WINDOWS
  [operating systems]
  "multi (0) disk (0) rdisk (0) partition (2) \WINDOWS="Microsoft Windows XP Professional "/ noexecute = optin/fastdetect
  "signature (ac516a5c) disk (0) rdisk (0) partition (1) \WINDOWS="Microsoft Windows XP Professional own "/ noexecute = optin/fastdetect

  I looked towards the top of this help page, but for now I'm unlucky:

  http://support.Microsoft.com/kb/314477

  (The next steps I took by throwing from the Windows CD and go into the repair console)

  I tried to use the bootcfg /rebuild but the line to boot.ini for my secondary HARD drive still does not work.

  He gave me something like:

  [boot loader]
  Timeout = 5
  default = multi (0) disk (0) rdisk (0) partition (2) \WINDOWS
  [operating systems]
  "multi (0) disk (0) rdisk (0) partition (2) \WINDOWS="Microsoft Windows XP Professional "/ noexecute = optin/fastdetect
  "signature (ac516a5c) disk (0) rdisk (1) partition (1) \WINDOWS="Microsoft Windows XP Professional own "/ noexecute = optin/fastdetect

  I also tried to change the signature() to multi (0), but it did not work. (or try almost all possible permutations of disk() and rdisk() partition() 0 to 2).

  I also tried to use expand F(dvd-drive):\i386\ntkrnlmp(I_have_a_duo-core).ex_ D:\windows\system32\ntoskrnl.exe and a few other combinations, but I when I login as D:\windows simply, it fails to extend with a message like "could not develop" or C:\windows I get "restricted access".

  I have not yet tried CHKDSK/r, but since I did a clean install on a newly formatted drive... I don't think it would work.

  I've also marked the partition on the D: as active (in computer management), but it did not help me.

  I've done a first installation of windows repair, strangely, I couldn't fix this one... Still does not work...

  My default windows installation yet works very well & I see that windows has been installed on the D: but I'm ideas from how to operate the dual-boot, can someone throw me a BONE on what to do?

  Maybe try to do something with the Boot Manager (whatever it is?) Create a new partition and use it as a boot manager? I don't really want to do this, because if I made a mistake I will be unable to use my computer and dual boot should work without going through all this trouble... But I found this page: http://technet.microsoft.com/fr-fr/library/ee829686%28WS.10%29.aspx

  Could a clean install two HDD help? I hope I won't have to do...

  Someone has an idea?

  PS: I'm not such an advanced user so I need a solution step by step, thanks!

  Edit: I also noted that I can't see my new HARD drive in my BIOS... weird... SATA-0 is my old drive HARD 1 and 2 are my dvd 3-5 readers are 'off' and it doesn't seem to be anything that it is plugged in. I also have 4 bays for internal HARD disks. Now, 2 are busy.

  Edit2: I looked inside my case and enabled the good Sata in the Bios after a reboot it detected the drive correctly. Dual boot doesn't always work well... The fact that it was disable in the BIOS while I was installing the new HARD drive could change anything? Hmm...

  In case I wasn't clear enough: I had a windows XP Pro installed on my C:, bought a new hard drive and installed the same copy of windows on it (d). I think that should allow me to double boot between the two installs different. Even if for some reason I can't boot from one on my D:. Andrew, I do not understand why you so far physically disconnect the other drive, the point of the whole operation is to build a boot.ini file so that the BIOS knows that it y facilities 2 windows and you allow to choose (and not have conflicting problems between the 2 systems), someone correct me if I'm wrong? "Expand" the part of my first post made reference to one of the solutions provided by Microsoft in the first link that I have included in my previous post (but I can't seem to work).

  In addition, it is the procedure that I followed: http://www.ehow.com/how_5950826_boot-two-different-hard-drives.html

  (except I've had the first installation already done).

  Andrew "also, once a new hd is plugged on the pc & running, most of the BIOS will place (them) as 1st priority hd, set the BIOS to do this", you mean that by installing separately from windows on each unit when the other is not plugged in, I could choose what disk to start from defining their priority in the BIOS once they are all plugged back? It's too tedious (as I intend to move frequently between the 2 installs) and requires a computer to other users of the lack of computer knowledge. Unfortunately, it is not a viable option.

  EDIT: I DID IT! Hmmm... Well, I double checked in the recovery console, the path of the new HARD drive with the arc command Scan. Tried to start again with the MULTI (0) in my boot.ini and it worked... I also had my windows install CD in. Maybe that is why I could not start, windows needs the CD to complete the installation? Weird, I don't know what I did to the difficulty it... but hey, it works! Thanks for your ideas guys!

• Can I run dual boot Vista 32 and Windows 7 64? Can I use a upgrade disk to install the full version?

  original title: I have a simple question...

  Hello

  You can't do what you want to do

  32-bit to 64-bit is NOT a upgrade path if you have always wanted to upgrade 32 bit vista

  It must be done with a clean install with a final certificate

  and you need a full license of windows 7 to install windows 7 on the 2nd hard drive

  You can dual boot vista 32-bit and 64-bit windows 7, if the manufacturer of your computer provides windows 7 drivers
