ubuntu - During Windows installation it thinks that EFI partition is not in fat32, but it is in fat32


I have Ubuntu installed on hdd, recently I've converted that disk to GPT using gdisk and created EFI partition formatted in fat32 (right after convertion it was ntfs, but then I've formatted it into fat32). However, when I was trying to install windows to unallocated space on disk, it said that my ESP is not in Fat32 and asked me to format it into fat32. I have rebooted into ubuntu and checked partitions:



  1. ESP created during convertation to GPT (fat32, about 4 Mb used, 200 Mb unused)

  2. Restore partition created by windows (ntfs)

  3. ESP created by windows (fat32, about 4 Mb used, 96 Mb unused)

  4. MSR partition created by windows (unknown)

  5. Partition for data created by windows (ntfs or unknown, I do not remember)

  6. Linux swap

  7. Ubuntu partition


Windows version is 10, ubuntu is 16.04, I also have Ubuntu live USB in case I have to fix bootloader or something else. How can I fix the error?


EDIT: Now I've deleted the EFI partition and Ubuntu can still successfully load, also Windows now does not give error about ESP but it does not create one! It only creates Basic data partition and MSR partition, no ESP and no Recovery! It does not load after install, however Ubuntu loads because it has GRUB on my old HDD with Windows (this HDD is half-broken that is why I want to reinstall Windows to another HDD). I have literally no idea what is happening, any suggestions?



Answer



The only thing that helped is disconnecting my old dying HDD before Windows Installation. When it succeeded, I wanted to cry and laugh at the same time.

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
