Windows 10: Windows 10 Preview (10130) Clean Install On Vista System

    Windows 10 Preview (10130) Clean Install On Vista System

    First I would like to say hello to everyone on the forum. Second I have quite a few questions as to doing a clean install of Windows 10 Preview (10130) on my PC that has Windows Vista currently on it. First, will my PC support Windows 10? (Processor- Intel Core 2 Quad Q8200 2.33GHz that has Instructions as follows MMX, SSE, SSE2, SSE3, SSE4.1, EM64T all these are from CPU-Z, the NX or XD or Execute Disable Bit as per Intel website is supported and from what I have seen most of the time you have to turn it on on your own in BIOS? (, and the PAE I am not sure (how do I go about finding that out?) , Motherboard is Dell/Intel 0N826N A00 (A2 Rev. for Chipset and 02 for Southbridge). Bios is Dell version A05 (04/09/2009). I have 8 GBs of RAM (GDDR2), and Radeon R7 250 1GDB GDDR5. From what I have read is that the 10 Preview will check anyway, but I just want make sure.

    Once the above specs will allow for Windows 10 installation, here are the questions (I am planning on using the following tutorial Windows 10 - Clean Install - Windows 10 Forums ) :

    What do I do with the partitions as I am completly lost when it comes to that part? I have the following partitions currently: Unallocated Space, OS (C), (D) Recovery Click image for larger version.

    1. I want to install the 10 Preview over Vista that I currently have. What do I do with the partitions (Can I leave the Recovery with Vista just in case I want to go back to it [I also have a disk from the manufacturer with the recovery OS]? Do I need to create one for System Reserved?

    2. My PC doesn't have UEFI, and I doubt it supports it, I want to stay like it is when it comes to BIOS. Can I install 10 Preview and leave the BIOS alone?

    3. If I want to stay with BIOS instead of UEFI, I should burn the 10 Preview ISO to a DVD, and then boot from BIOS, correct?

    4. As for the NX or XD or Execute Disable Bit, this needs to be turned on in BIOS?

    5. I doubt that I have Secure Boot, Is this something that will prevent me from installing and running correctly the 10 Preview?

    Thank you so much in advance. Any input is appreciated.

    The mainboard doesn't help. What is the model number of the Dell PC? I checked a couple of models with this motherboard, and it looks like there's an A12 BIOS. I don't know what this bios does, as there's no release notes.. but given this machine shipped with Vista, my guess is WIndows 7 and Windows 8 compatibility are both in it.

    I don't know what your problem is with a more modern bios, but if Windows 10 isn't compatible with it, you won't have any choice.

    I have nothing against a modern BIOS version (UEFI), its just that the motherboard might. CPU-Z gives me A05 version of the Dell BIOS with 04/09/2009 date.

    Why would the motherboard have a problem with a BIOS that Dell has explicitly released for it?

    And again, what is the Dell model number of your system? The motherboard model does not tell me anything for sure.

    Ok, I figured out that I can stay with the same BIOS that I have now, and that my hardware should be able to run Windows 10 Preview. Now the question is if I choose to install 10 Preview on OS (C: ) partition without formatting, it will replace Vista and make a Windows.old right? Also, what do I do about the System Reserved partition? If I will not format the OS (C: ) partition, will Windows 10 Preview install make that partition, or there has to be unallocated space in order to do that? If I delete the Recovery (D: ) Partition that has VIsta Recovery from the manufacturer on it, can I still clean install Vista with a Recovery DVD (that has Vista OS on it) that I received from the manufacturer (Dell) in case I don;t like the 10 Preview?

    I have Win10 on a Dell Inspiron 530S that originally came with Vista. I fully cleaned the HDD then installed Win10, now on Build 10130. I noticed I have a Windows.old Folder dated the day after installing the current build so I suggest saving the Windows.old Folder to another location after installing Win10 if you want to get Vista back or an update to Win10 may overwrite it. Since Win10 will do a clean install over Vista it's necessary to have that disc from Dell to go back to Vista. When 'downgrading' I prefer to boot to a GPARTED disc to first delete all partitions from the drive then boot the Restore disc. The download is an .iso file used to create the bootable disc.

    Berton, So once I am in the Partition selection step in Win 10 installation, I should just delete both Partitions and the deleted partitions will create Unallocated Space, and when I choose the unalocated space to install 10 on it, I will get the System Reserved partition automatically? I have the Recovery DVD from Dell, so I will be able to clean install Vista from that DVD in case I want to go back, even though having deleted the Recovery (D:) partition?

    Delete all partitions, including the recovery partition, since you have a recovery disc (if you ever want to go back to Vista).
    Don't create any partitions, just click Next. Let the Windows installer create and format the partitions it needs.
