Windows 10: How to gain boot speed after uninstalling ubuntu/grub2 from dual boot

Support needed for efi boot partition related issues..

So i recently installed ubuntu 19.04 in my ssd by shrinking some free space. I did it manually in ubuntu installer .. everything was great.. So i came to know ubuntu has no driver and support officially from amd . So i decided to uninstall . (Here one thing to mention before going to the context . Grub2 was my main bootloader, windows 10 listed there as "windows bootloader manager" or something like that . when i click windows , it goes to old very old bootmenu of windows with black background and shows two os of windows . one is windows 10 and another is Microsoft windows. both the entry pointed to same windows10 os . )

I manually cleared the ubuntu partitions .. i opened msconfig i saw that two windows boot entry . both are same , i was actually on "Microsoft windows" not on "windows 10" as i selected it when booting but both are same . so i set Microsoft windows default . and deleted the other one . set back to windows bootloader through cmd . now the ugly windows bootloader is gone .. it continues to show msi logo while loading as normal . now the issue is .. since it was very very fast and responsive to boot before the ubuntu .. now when i try to boot ..a blackscreen stays for 15-20 seconds .. and then msi loading appears and windows lockscreen appears ..as normal ..

why it is taking long .. is there any problem created in efi boot partition ? and how to fix it (i don't want a fresh install of windows again) ?

i deleted efi folder of ubuntu ..but somehow ubuntu entry is still in my eufi advanced boot option

dual boot xp and ubuntu

I had that problem a few months ago, but dual-booting is really easy. I am currently dual-booting Vista and Ubuntu 8.04 Hardy Heron. Use this website here for a guide to dual-booting XP and Ubuntu: APC's September 2019 issue is on sale now! | TechRadar (I actually did not use this guide at all, but I did pretty much the same thing!)

If you are unable to get your boot working with this guide, reply to this message, and I will write out a step-by-step guide, but it will involve you already having a partition set out for XP (as in you are not already using your entire hard drive space for XP alone.) Even though I write the guide with experience from Vista, it will work with XP
