Creating a dual boot with Windows and Ubuntu when you have UEFI

People on many blogs say that you have to disable secure boot when you have UEFI and want to install Ubuntu alongside Windows 8 or 10.
Not necessary. You don't even have to switch to Legacy boot.

The basic concept to understand is, that if you have UEFI, you'll have to tell the boot manager where to find your boot file. That's all.

After a lot of searching and ending up at all the wrong blogs and posts, I finally found this post. Worked perfectly!

The steps are:

• Install Windows, leaving a separate partition for Ubuntu
• Install Ubuntu on that partition
• Reboot and enter BIOS screen
• Follow the steps here about selecting grubx64.efi
• Save and exit BIOS

That's it! You've got a dual boot system. Grub will show you the options for booting into either Windows or Ubuntu.
If anything goes wrong, you can always press F12 when starting your computer to see the boot options.

Oh btw, don't disable secure boot. It's a very important feature that prevents your system from getting infected at boot time, by malware that might be in an external drive that's connected to your PC at boot time.

Our Income tax website has a perplexing error message

I logged into my income tax e-filing account yesterday, and saw this message: "You are not authorized to view this page because either your bank details of your PAN and profile details are incorrect or these details have not been passed onto e-Filing. Please contact the owner of the information for details".

I was completely perplexed. I had filed my taxes correctly, so why this message? I couldn't even access my dashboard and didn't know what to do.

A bit of Googling revealed that few other people had faced the same issue since 2014. One of the answers on a forum said that this message shows up when the website is undergoing some routine maintenance, and we should check back after six to twelve hours.

I logged back in the next day and sure enough, everything was back to normal.

Phew!

Whether it's a routine website maintenance or too many connection requests to the server or because there's an actual issue with the details not matching, I hope the message could be changed to display something that specifies what the actual issue is, so that we could be informed of it and do what is necessary to fix it. For example:

• If it's routine maintenance or too many connections to the server: "Routine website maintenance ongoing. Please check back after few hours".
• If it's a problem with the bank details: "Your bank details for <bankName> are incorrect. Please ensure that <problem> is fixed by <solution>".

This is for all of you who were perplexed by this message and didn't know whom to ask. Hope it helped. In most cases, you just have to wait a while before you try logging in again. Otherwise, you can always contact the income tax helpline to find out more.

 

Update 2020: The issue still seems prevalent, as shown in the comments below. I hope contacting the relevant authority or submitting feedback or submitting a grievance or contacting your bank to mention this problem may help resolve the problem faster.
