Windows 10: Windows 10 Clean Install - Dell Inspiron BIOS - Legacy Option

Hi,


A few days ago I replaced my hard drive with a solid state drive and did a Media Creation Tool clean install to a Dell Inspiron. I changed the BIOS Boot Menu options to Legacy, Secure Boot disabled, Legacy Option for USB boot to use the Tool.


Since then, after doing the clean install, I can't change the BIOS Boot Menu back to UEFI and Secure Boot. The laptop boots into Windows, and no obvious problem is indicated, but it is not as fast as it should be. Since the Clean Install I've updated the BIOS to Version 4.4.0. The UEFI settings option does not appear in Troubleshooting within Windows.


I'm contemplating redoing the Clean Install with the Tool, which I hope will fix the boot to UEFI and re-enable the Secure Boot.


I'd appreciate your help to see if this is the best method.


Thanks.

:)

 

Clean install of XP on Dell laptop?

My friend has an inspiron laptop from dell. He got it with Vista preinstalled on it, but wants to switch back to XP. He got an XP Pro CD, but when he inserted it, the "Install XP Now" option was greyed out. I thought it might be dell trying to make life difficult when reinstalling windows. *Confused Any advice??

If I formatted the hard drive for him, NTFS, would I be able to clean install XP or would the prob still be there?

Thanks in advance

Windows 10 Home on Dell Inspiron 3847 will not update to 1709

I have two identical boxes with same issue- Windows 10 Home will not update to 1709. Here are the hardware specs & steps taken to fix the problem:

Dell Inspiron 3847
Windows 10 Home ver 1607 OS Build 14393.1944
Intel Core i5-4460 3.2G
12GB RAM
Integrated Intel HD Graphics 4600
1TB SATA HDD

It downloads and attempts to install the latest updates then several hours later reverts back to where it was.
So far:
- installed & ran Windows Update Troubleshooter & taken the steps that it suggests
- renamed Windows 10 upgrade folder and downloaded the latest updates
- deleted the software distribution folder & downloaded/installed again
- ran windows cleanup and deleted all those files
- tried stopping & disabling the windows update service to prevent it from continuing
There is licensed software so a clean install is out of the question.

These PC's are installed in a restaurant and when this happens the whole place shuts down during lunch & dinner. Any suggestions would be greatly appreciated
