    Having problems installing win 10 from bootable USB


    I created a bootable USB of Win 10 from Brinks tutorial, I just built a new system, I went into the bios to make sure the boot order had USB,I changed the boot order to USB.

    I rebooted with the bootable USB I created and I got to the "Install Windows" screen then it showed me the partitions on my SSD with has my old OS on it.

    I tried to format the first partition as it was the largest and I assume that is where my old OS was installed but it won't let me format the partition. Below are the screenshots of what I get. I'm doing something wrong but not sure what??Having problems installing win 10 from bootable USB-img_5996.jpgHaving problems installing win 10 from bootable USB-img_5997.jpgHaving problems installing win 10 from bootable USB-img_5999.jpgHaving problems installing win 10 from bootable USB-img_6001.jpg

    For a Clean Install it is RECOMMENDED to detach ANY other disks [ Internal & External ] FIRST and then during installation delete ALL Partitions which will leave a SINGLE Unallocated Partition in which toClean Install Windows.

    Another factor is are you going to install as UEFI or Legacy BIOS. Refer to > Clean Install Windows 10

    I hope this helps.

    The only disc connect to my computer now is the SSD that I had my OS on. whenever I installed windows in the past, many times I never had this issue so I don't know what the difference is between MBF and GTP ?? Not sure which one is best to use.

    I did find YouTube video showing how to convert MBR to GTP but would like to understand the difference before converting.

    I would prefer to wipe the SDD so it has nothing on it and then use my bootable USB drive to install the version of windows that is on it. I looked at the link you sent and I'm not sure how to do the following

    Boot to the UEFI firmware settings for your motherboard, and enable or disable UEFI or Legacy BIOS (CSM) mode for how you want to install Windows 10.

    Usually it will be set to UEFI mode by default if supported. You may need to read your PC's or motherboard's manual for its specific instructions on how to change this setting.

    The motherboard I have is the MSI MAG Z790 Tomahawk WiFi

    Hello @Eaglepi,

    - During Boot [ POST ], you will see TWO options on the USB drive.
    - USB UEFI [ Name ] and USB [ Name ].
    - Select USB UEFI [ Name ] if you want to Boot as UEFI-GPT, or select USB [ Name ] if you want to Boot as Legacy-MBR.

    This may help you decide which one is best suited for you:

    That is what was confusing to me I didn't get that screen that asked me which way I wanted to install windows, I just got the "Install" screen and when I clicked install I go tot he screen that shows my partitions. I tried it again and this time I just del so I had 1 deleted the 2 partitions I had so then I was left with 1 unallocated volume. I clicked next and it appears that windows 10 installed it rebooted I removed the bootable USB and now it is setting up Windows 10,

    Not sure if what I did was the right way but it is installing now.

    Thanks for your help

    Old Legacy BIOS uses the Master Boot Record (MBR) partition scheme. This in Windows 7 or later means a small partition with system data (not visible in File Explorer) and a large NTFS partition for Windows files. This is what you see on your first photo. Your USB flash drive is propably created with the newer GPT (Global Partition Table) scheme and it cannot use MBR disks to install Windows. You must delete all partitions and then click Next. Windows Setup will automatically set the disk in GPT mode and create several small system partitions and the large NTFS partition for Windows files. If you have some files you want to keep, you should backup the data first by connecting to another computer or create a Legacy BIOS (MBR) USB flash drive and install Windows 10 without formatting. This will move old Windows data in folder Windows.old

    The Partition Style selection is made from the USB [ During POST, maybe by pressing F12 ] prior to ANY installation screens.

    After installation, to check which Partition Style is installed, Copy & Paste the following command into a CMD Prompt and press Enter. It will be under Partition Style.

    Code:
    
    PowerShell "Get-Disk"

    I hope this helps.

    I thought I replied to your last post but I must have not hit send, I didn't get that black screen asking me to chose which version to install. It brought me back to the screen that said "Install" I clicked it and was back at the screen that showed my partitions. I just deleted the 2 I had and clicked "next" then windows started copying files as it normally does when you do a clean install.

    After a little bit it rebooted so I took the Bootable USB out and when it booted it just started to setup windows 10, I chose win 10 Pro because that is what my key if for that I bought from MS, so now it is hours of installing all my programs...........lol

    Thanks for your help !!

    Paul,
    It is too late to press F12 before I boot to the USB, Windows is already installed. Right now I am copying files to my backup darive and that will take a long time. when I am done I will find out what Partition style I have.

    It's too late I already installed window 10 and now I am copying files from my old HDD's to the new SDD's This will take a few hours and when that is done I will find out what type of partitions I have and let you know.
