HP ProBook 4520 s - dual boot between Win7 64 bit and Ubuntu 10


I just got my new HP ProBook 4520 s a few days ago and:

(1) there were 32 bit Windows7 professional pre-installed / pre-loaded

(2) it comes with the TWO 32-bit and 64-bit Windows7 professional DVD HP (I guess versions OEM HP)

(3) the HD have 4 partitions in the following order

score A 3 a) named SYSTEM

3 (b) the parition where Win7 is installed

(3 c) HP_RECOVERY partition

partition HP_TOOLS 3D)

I did a lot of dual-boot in the past years, but my question is really related to maintain the HP diagnostic tools that arise before even that any operating system is loaded... and diagnostic tools are those of the HP_TOOLS partition. For example, when I ran some diagnostic tests, after completing the tests and the boot of Win7, I see in the HP_TOOLS partition, in one of its directories, a .log file recently updated with the results of diagnostic tests. I want to assure you that I can still run powered on the laptop even after dual-boot diagnostic tools.

Now, since I have the DVD 32 - bit and 64 - bit, I decided I want to dual-boot between Linux and 64 bit Windows7 professional. So here's what I've done so far:

(A) has reduced the volume of Win7 Windows computer management disk management

(B) install Win7 64 bit on top of the existing 32-bit Win7 partition, format this partition during the installation. So no more HP utility and on the installation of 64-bit programs.

So now I have Win7 64 bit installed and professional pre-activated since it's the same notebook. Then, I realized that I really need to delete the HP_RECOVERY partition since you can have up to 4 primary partitions. So by deleting the HP_RECOVERY partition, I will be left with 3 primary partition, then I can create an extended partition to contain other partitions for Ubuntu, etc...

But before I delete the HP_RECOVERY partition, I want to know:

*) When starting, before even that any operating system is loaded, HP you shows options like "Diagnostics" and "recovery". How is the computer HP laptop knows that diagnoses are in the HP_TOOLS partition? How the laptop HP ProBook 4520 s knows that recovery is in the HP_RECOVERY partition?

*) Since I have the DVD of Win7 HP (32-bit and 64-bit), I don't really have the HP_RECOVERY partition. If I delete the partition, what will happen to this start screen which gives you the possibility of "recovery"? Of course the recovery option won "t work and I don't like, but will remove the partition HP_RECOVERY won't let me boot into Win7, or any OS besides? for example it does not validate there HP_RECOVERY partition to a place before loading Win7?

*) Then, I want to install Ubuntu, and preferably Ubuntu (or Grub also) overwrites the MBR. I prefer Grub on EasyBCD. I can easily change the configuration of grub so I can dual-boot with Windows7... But again, my question is, where does HP maintains information about diagnostic tools that they are in the HP_TOOLS partition, like the option of the diagnostic tool loading via BIOS before even any OS is loaded. Is that information in the MBR, or is it in the partition named SYSTEM?

Summary of the questions are therefore:

(1) where HP keeps its information that diagnostic tools are in the HP_TOOLS partition? It is in the MBR, or the SYSTEM partition, or is it stored in the BIOS hard coded to load more precisely from the location of the partition? I want to keep the ability to run Diagnostics even after you have a dual-boot installation with grub in the MBR.

(2) deleting the HP_RECOVERY partition will prevent the workbook from loading correctly before moving to Win7, Ubuntu or any other OS?


Just find the answer to my original question:


He uses the EFI interface and seeks a partition named HP_TOOLS, which means overwrite the MBR will not affect the operation of the HP diagnostic tools.

  • Dual boot between the preinstalled Vista and Linux

    I think installing dual-boot between Linux systems, for this I need to repartition the hard drive and reinstall vista and vista pre-installed that I na? t have the disc so that I only have recovery.

    Assuming that the operating system is on the machine in a hidden partition is it possible to make as if I change the custom of available to partition I lose the data recovery. Also, if it's possible here is a recommended distribution to use.

    As far as I know the recovery system resides in a hidden partition.
    On my machine, it is/dev/sda1

    After this partition (the remaining rest) there is a large partition with Vista on it.
    On my machine, it is/dev/sda2

    You can resize (i.e. minimize) / dev/sda2 partition of your distribution tool.
    Then, create a scope/dev/sda3 partition

    In/dev/sda3, you can create partitions for your Linux system

    On my machine, there is no need to reinstall Vista; Dual boot works fine.
    After the Vista partition with partition tool of opensuse 10.2 resizing Vista has conducted an audit of file system

  • Dual boot Win 7 64 bit and XP Pro 32-bit (win7 installed first)

    How can I set up: dual boot Windows 7 Ultimate 64-bit and Windows XP Pro 32-bit (Windows 7 installed first)? I have Win7 on a 2 terabyte HARD drive, with another 1 terabytle internal HARD disk and two 1 terabyte external hard drives. I have an Intel Core i7 960 @ 3.20 GHz, 20 GB of RAM. I want to keep Win7 on 2 TB drive and add WinXP on the other 1 TB internal drivw in a configuration dual-boot. The other two drives 1 TB external would be used for backups and data. I would like to be able to boot XP because I have many applications running on XP wothout having compatibility problems.  The two Win 7 and XP are complete versoins. Or that I would be better to try a virtual configuration?

    Are you aware that you can install the free XP mode on your Windows 7 system?  Once installed, you can launch in 15 to 30 seconds as a task under Windows 7 and run your XP applications without having to reboot.  It works fine as long as you can live with the graphics.  The graphics of XP Mode are great for business applications.  This would be my first choice.

    You will probably get the positions, which suggests a way to install XP and then download a program or two and patch in some places.  But for me it's much simpler to just create a small partition of 30 GB and make a 30-minute "quick and dirty" installation of a second absolutely minimal copy Windows 7 in there.  This will get all start after installing XP, if you decide to go this route.  It's not like intelectually sophisticated as more involved patchwork approach, but it is faster and easier.  As my professor of chemistry at first year said "anyone can make things complicated; He needs to make things simple.  I think the professor was very clever!

    I hope this helps.  Good luck.

  • Boot with Win7 32 bit and Satellite L450-36 problems

    A friend has a laptop Toshiba Satellite L450-36 Windows 7 32-bit which he thinks has been hit by a Virus. He went to use the laptop a few weeks 3 + ago and concluded that it would not initialize. Now, he has 3 daughters who, before this problem, much used YouTube and say that they were able to see updates Adobe Flash Player appear on the screen at regular intervals, but they have deleted the. When he came to talk about the problem for me, I offered to watch the machine that I have some disks that can cure or at least let me save records Paragon Rescue Kit, Avira Anti Virus Rescue Disk, AVG Rescue Disk & others.

    When I turn on the machine I get a screen with boot Toshiba Leading Innovation one
    Press [F2] for INSTALLATION, press [F12] to the lower boot device selection menu. I leave the machine in operation and a window pops up let me the choice of {HD1}, , , but nothing happens when I select one, then I stop the machine and start again, this time by pressing F2 which takes me into the BIOS. I put in a cd, Paragon Rescue Kit 11, arrived on the BIOS and the CD starts. I did the same thing with the Avira Anti Virus system and it found 4 infections. He then lets me copy all my friend (s) files on an external hard drive, which allows me to complete objectives.

    I started the Recovery CD/DVD Toshiba product and I get a Windows loading files message followed by a bar of Microsoft Corporation loading under him and then there is a black screen with a cursor on it. I did the same thing with a system Windows 7 32-bit repair disc and get the same result black screen empty.

    I am retired and to my knowledge has been gained since the Commodore 64 days, then Amiga and PC now, but it isn't enough for me to fix this problem. I found very frustrating to be able to use a Linux program and see all the programs on the PC, but not actually being able to restart it, and start them! I could probably Boot & Nuke the hard drive, but my friend wasn't t provided with a disc of Windows 7 o/s system couldn t so re-installed without buying again.

    I would be very grateful for any advice on how to get rid of the HD1/FLOPPY/NEXT HD window and a solution for the portable computer so that it starts properly. I took pictures of different screens on the laptop that I could pass if they would help.

    In my opinion, you should remove the HARD drive and connect it to another computer and perform low level set in shape and just delete everything. You can use a tool like this and after doing this put back and try to install the original recovery image using the recovery disk.

    In the past I ve never had these problems, but I think it's the best way to remove all the viruses or malicious applications.
    Test it and thanks for posting comments.

  • Dual boot Win7 32 bit and the 64 bit Win8?

    In anticipation to Windows 8 be accessible to the masses, I would like to know what are the possibilities to install 64-bit Windows 8 when Windows 7 32-bit is already installed.

    Would Windows 7 32 bit and all the 32-bit drivers need to be reinstalled with the 64-bit versions?

    Which means a complete reinstallation of parameters/data and applications existing/installed all be kept or partition the hard disk drive and to start new to new is the only solution?

    Or install another hard drive would be more appropriate?

    In anticipation to Windows 8 be accessible to the masses, I would like to know what are the possibilities to install 64-bit Windows 8 when Windows 7 32-bit is already installed.

    Would Windows 7 32 bit and all the 32-bit drivers need to be reinstalled with the 64-bit versions?

    If you dual-boot Windows 7 32-bit and 64-bit Windows 8, you will need to install the 64-bit native drivers. Windows 8 and 7 64 bit do not support 32-bit drivers.

    Which means a complete reinstallation of parameters/data and applications existing/installed all be kept or partition the hard disk drive and to start new to new is the only solution?

    Yes, you will have to reinstall applications too. You will be able to migrate your personal files and settings by using the Windows Easy Transfer utility.

    Or install another hard drive would be more appropriate?

    You can install it on another partition or hard disk. If you are installing on another partition or hard drive, you will need a full version of Windows 8.

    What an adventure!

    As you discovered, you must completely format the drive as one or the other (GPT or MBR).  You cannot format a GPT partition and the other in the MBR.

    I wonder if you had back and disabled the legacy mode, if W7 would let you install on the GPT - or partition if the disabling legacy mode would also have permitted secure boot.

    In any case, it's water under the bridge.

  • Dual boot Win 7 64 - bit of complications and Win10

    At the present time, I have a dual boot system running Windows 7 and the preview to win 10 (on a separate SSD). Everything works OK.

    I want to install a new motherboard and load a 64 bit version of Windows 7 (new battery).  And... I want to use the SSD for the final version to win 10.

    If I understand correctly, I will have to remove my HD Win7 and win 10 SSD to install the 64-bit versions. I have a DVD 64 bit Windows 7, but I guess I'll have to get a Win 10 ISO.

    I would like to reinstall a large part of my Win 7 backup files and programs for the 'new' 64-bit Windows 7. Then I carefully would focus on files and programs to victory 10 64-bit in the car.

    What is freaking me out, is the vision of key programs does not work with the 64-bit versions. If all goes well, I read that a large number of 32-bit programs running on a 64-bit system.

    With a bit of luck, I have to burn (in TB) storage so I can back up carefully, but that is not good if the stuff saved refusing to work with a different system.

    I'd love a lot of comments on my strategy. I'm too much of a big deal, or it's going to be a nightmare?

    Thank you!

    Kurupa salvation,

    I'll be happy to help you with the problem you have with the computer. I understand the frustration when things do not work as it should.

    If the program is specifically designed for the 64 bit version of Windows, it will not work on the 32-bit version of Windows. (However, most programs designed for 32-bit version of Windows operate on 64-bit Windows version).

    Device drivers designed for the 64 bit version of Windows do not work on computers running a 32-bit version of Windows.

    Hope this information is useful. Just reply in case you have any other questions. I'll be happy to help you.

  • I am dual-boot between Windows 7 and Windows 8, but fear the time required to start,

    I am concerned about the time it takes my computer to start
    I have a system dual boot with Windows 7 and Windows 8, and it takes several minutes to decide to show me the screen to decide which OS to use, and then it restart and takes some time to start [the chosen OS
    Isn't time that Microsoft has put some of their skills as computers immediately when starting lit instead of focus on trying to outdo all other systems with stuff
    By the way, I have the same comment on the closure, it takes some time to completely close down--another point for Microsoft to put the attention

    Unfortunately, the processor is just at the level of the minimum required. In addition, RAM is 4 GB, in which folder page size will be approximately 8 GB. Norton 360 scans all files prior to execution, even if it's a system file. This is the reason for the delay.

    Try to upgrade the processor and the rest will be solved.
  • Dilemma of dual boot Win XP SP3 Pro and Windows 8 Pro

    At this time, April 2013, I expect to build a desktop system dual boot with Windows 8 Pro for the current and future capabilities and Win XP Pro for continued use of legacy aps favorite who will not run on Win8. It turns out that the disc formats are a problem. The Win8 64 bit needs a partition format GPT to install 32-bit XP or XP Pro needs a format MBR partition to install. No OS will share the same format and a main drive cannot be formatted and partitioned in a type of format or the other. What to do? !! Two computers are not an acceptable answer; I want a 'box '. In addition, not interested in XP Mode embeded in Win8 or 'virtual machine '. One suggestion has been to run the operating system on separate disks. For me, this means that 2 SSD is to get performance on the two operating systems. Also, to move from one OS to another, you must restart; catch the key bios entry; change the boot sequence; Save/quit; and reboot. (Awkward!). So what to do with the data and documents - one NAS file storage (for example, disk WD Live 'cloud')? There's good news to have? Are there recent usability solutions to help solve the dilemma of the dual boot? A boot manager will really help and there a good "gift" there Boot Manager? Thoughts, anyone?

    I have a custom system DIY mb Gigabyte Z77, processor i7-3770, running a fresh XP Pro SP3 Edition Builder.

    The drive letter is not critical since XP, Windows 8 will still start as C: (even if the partition is Z: in Windows XP).

    I pre-formatted Windows 8 partition before installing Windows 8 (named volume: Windows 8).

    Then, when you reach the screen "Where install" during the installation of 8, choose the partition of Windows 8.

    You can view other things is the BIOS, look for compatibility / legacy mode option.
