linux - Windows 8.1 Advanced startup options disappeared


OK so a bit of background: I need to disable driver signing because I need to install a modified driver so that I can hook up my PS3 controller.


I have a dual boot setup with Mint 17 and windows 8.1 x64 using rEFInd as the boot manager because MSI hates Linux.


Now I followed these various steps but



  1. when I try to get into the advanced startup, it simply does not exist, at all. I have options to shut down or go into uefi, none of the others

  2. using Driver Signature Enforcement Overrider did nothing, on restart or digitally signing.


  3. Tying command line bcdedit /set TESTSIGNING ON spews


    The boot configuration data store could not be opened.  
    The requested system device cannot be found.


So what I THINK is going on is that it cant find the bcd store, and doesn't store the boot options.


So how do I either



  • install an unsigned driver without rebooting

  • get into test mode without requiring boot configuration

  • set windows boot settings in rEFInd from linux

  • sign a driver locally



Answer



Ok so I haven't exactly figure out what happened to the advanced options


But I did solve my problem



  1. need a windows 8 DVD

  2. boot the dvd and click on repair

  3. go to troubleshoot -> advanced options -> command line

  4. run diskpart

    1. list disk

    2. sel disk 0 select your drive with the efi partition (replace 0)

    3. list vol

    4. sel vol 1 now select the drive with the efi partition

    5. if it does not have a drive letter, assign one assign letter=z



  5. And this is the crucial part if you are dual booting. You need to specify where the BCD file manually for bcdedit to stop throwing that annoyin error I mentioned

    1. bcdedit /store z:\EFI\Microsoft\Boot\BCD /set {default} loadoptions DDISABLE_INTEGRITY_CHECKS

    2. bcdedit /store z:\EFI\Microsoft\Boot\BCD /set {default} TESTSIGNING ON




For those interested the 2 key parts are specifying your bcd store manually, since in my case the dualbooting screwed things a bit, and specifying {default} so that it knows to install it in the OS loader not the Boot manager

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...
