uffbros Posted October 14, 2018 Share Posted October 14, 2018 I have a co-workers laptop made in 2012 and came with Win 7 home. The BIOS has no options for legacy or UEFI. I would say it is Legacy BIOS. If I put my Win 10 USB into it which is setup for UEFI install it is recognized in boot menu but when I select it it goes straight to the installed Win 7. So I go and reformat with the other option Rufus offers which is MBR and it only offers NTFS as a choice. Wouldn't that be the choice for a legacy MBR BIOS? Win 10 can only see fat 32 correct? So how can I get this USB drive formatted correctly to install Win 10 on a legacy non UEFI GPT computer? Shouldn't RUFUS do the job? I always use RUFUS but this is first time I can't get boot menu in that laptop to see anything but UEFI GPT but that when selected goes straight to the installed OS,which was Win 7.

Lysoform Posted October 14, 2018 Share Posted October 14, 2018 Have you tried to use diskpart to format your USB and then copy your Win 10 installer into it? Link to comment Share on other sites More sharing options...
knowledge-Spammer Posted October 14, 2018 Share Posted October 14, 2018 have u tryed with program like PowerISO or daemon tools mount the iso and then install ? y use usb ? Link to comment Share on other sites More sharing options...
MrZeb Posted October 14, 2018 Share Posted October 14, 2018 @uffbros Start Rufus and press the hot key ALT + E only one time let the tool format and transfer the Windows 10 ISO to the flash drive again. ALT + E enables dual boot mode this creates the flash drive boot in a way that will work fine in computers with UEFI or legacy Bios. Link to comment Share on other sites More sharing options...
zinoswink Posted October 14, 2018 Share Posted October 14, 2018 I've never used anything besides UltraISO for a Windows flash drive installation, and it's worked every time. I've used the same bootable flash drive for both UEFI and legacy bios installs without issue. Link to comment Share on other sites More sharing options...

If you decide to custom (or clean) W10, the file called install.wim will be larger than 4 GB (limit FAT32). Bios (legacy) ===> MBR UEFI ===> GPT Don't forget one thing : your hard drive (or SSD) and the usb key must have the same table partition. Otherwise it won't work !

Ecarion Posted October 14, 2018 Share Posted October 14, 2018 In that case @MrZeb explain me one thing : Why W10 has refused to finish (or cancel) the installation ? No I haven't forget this trouble (neither the error message from W10) and yes I had try several times. Then on the moment, for me it was the lonely solution (GPT for the both). As today I don't think something has changed. But it doesn't matter because I had disable the UEFI several years ago. At least I can confirm Rufus work's fine.

On Windows 8.1 or Windows 10 in UEFI mode simply use Diskpart to clean the disk (if not new and empty) then point the installation to the drive and let Windows create the needed partitions, Windows will set the disk as GPT and create all the partitions that the OS needs.

Kalju Posted October 14, 2018 Share Posted October 14, 2018 If this laptop was made in 2012 and came with Win 7 home, then what about UEFI you are talking about. There should be only a Legacy BIOS boot and I recommend to make MBR partitions and there should not be any problems. As far as USB NTFS formatting is concerned, some older USB devices can not really be formatted to NTFS, you need to use FAT-32 and it also works without problems in this case. You do not need to use Rufus, simply unzip the iso and copy all files to USB and then use the BIOS menu to start from USB. In the boot settings is not needed make any changes, simply select manually USB or DVD or what you need and click ENTER. Link to comment Share on other sites More sharing options...

mikie Posted October 14, 2018 Share Posted October 14, 2018 Should do an upgrade install to win7 from file explorer with the iso. Even though microsoft said the 'free' upgrade ended long ago, it still is a free upgrade. Sometimes you can use the Recovery/Reset to get it activated with a fresh install but not always. Once activated for the first time you can re-install it anyway you want. Link to comment Share on other sites More sharing options...

uffbros Posted October 14, 2018 Author Share Posted October 14, 2018 I got the Win 10 installed with another flash drive. The other one works fine but can't explain why it won't show in the boot menu. It works for everything else within Windows. @Kalju ....I thought I explained it that way....Yes it is Legacy but since it wasn't working using the MBR method I tried the UEFI..I tried them all. Troubleshooting I guess....In the end it had to be the flash drive. Link to comment Share on other sites More sharing options...

It's true that USB does really sometimes such a tricks. I have also couple of them, what can be used for data transfer, but not for installing.

Some flash drives report as Removable others as HDD and in some older machines the way the BIOS detects the flash drive (Floppy, HDD, ZIP) can also affect the boot process.
