Suddenly slow boot time

Question

Hi everyone, first post noob here.

I removed Ubuntu from my laptop about a month ago. All traces are gone from BIOS.
It used to take 10 seconds from pressing the power button to the login screen (before dual boot, and with dual boot), but now it takes over a minute. My BIOS start time is still 2.5-3 seconds, but splash screen to login takes an age. I did a fresh Windows install, no difference. I have nearly everything turned off in task manager startup.

I know this question's probably been asked before, but I've tried everything and would appreciate any help and advice.

Answer 1

You have a bunch of unused Recovery partitions taking up space. The 20gb one is so large it must be a Factory Recovery partition but only HP still has those. I cannot advise which to delete because we don't know which one is being used and it could lose the bootable repair tools, although you can always use WIndows 10 bootable installation media for repairs.

I would look over and consider doing this tutorial for a gold standard Clean Install which compiles the best possible Install of Windows which will stay that way as long as you stick with the tools and methods given, has zero reported problems, and is better than any amount of money could buy: http://answers.microsoft.com/en-us/windows/wiki...

The reason I suggest this is because you're building up a disk junkyard, and also that no one who has adopted the install in the above link has ever come back to report further problems I've seen, including another version failure. This is because everything in Windows 10 is dependent upon the quality of the install, especially Version Updates which will choke on lesser quality installs, and there is no possibility of problems if you stick ONLY with the steps, tools and methods in that tutorial.

It is also one of life's great learning experiences that will permanently make you the master of your PC because you will learn everything that works best and how to keep it that way.

When I rebuild the BCD and it ask me to add installation to boot, i press y and it says it cannot find the file path.

When I try to do it manually, i get as far as "ren c:\boot\bcd bcd.old" and it says invalid syntax.

Here's the expanded disk management.

Hi Shane -

Unfortunately I can't read any of the labels in your Disk Mgmt screenshot. Please post another screenshot of Disk Management, which I read like a doctor reads X-rays. Follow the steps here so I can see everything needed to advise you: http://answers.microsoft.com/en-us/windows/foru...

Did you try rebuilding the BCD?

Hi Greg,

I had a grub dual boot. I removed all traces of Ubuntu in DiskPart. There is no sign of it anywhere. In Bios, the only boot option is windows, the grub is gone. I have attached a screenshot of my disk management. I'm not sure what the first 4 partitions are. should I get rid of any of them?

Hi Shane. I'm Greg, an Independent Advisor.

How was Windows dual booted with Linux? Did you add Linux to the WIndows 10 boot loader using EasyBCD (best method) or add Windows 10 to Grub which may still have remnants that are interfering with boot?

Did you wipe the drive with Diskpart Clean command https://www.tenforums.com/tutorials/85819-erase... to remove old code before reinstalling Windows doing a gold standard Clean Install in this link which compiles the best possible Install of Windows which will stay that way as long as you stick with the tools and methods given, has zero reported problems, and is better than any amount of money could buy: http://answers.microsoft.com/en-us/windows/wiki... ?

If you merely Reset or reinstalled without wiping code from the boot sector then that's why the reinstall was not effective in this scenario.

You can also try rebuilding the BCD first:

In the future here's the best guide for dual booting with Linux:

Even better is to use separate hard drives with each unplugged when you install the other, then boot WIndows via UEFI BIOS' Boot Priority set for BIOS Boot manager, boot the Linux in legacy mode using BIOS Boot menu choosing Linux HDD. This keeps them independent to avoid blowback like this from GRUB.

I hope this helps. Feel free to ask back any questions and keep me posted. I will keep working with you until it's resolved.
