Can not boot Windows on Legacy BIOS after installing Ubuntu on UEFI Long story short, I installed ubuntu while I was watching netflix and feeling very lazy, and may have lost all my windows 7 files.  Quick summary:    -Windows 7 was installed on Legacy bios and I installed ubuntu on UEFI bios -ubuntu installer didn't detect any other OS on my computer and wanted to write over the disk, so I had to manually edit the partition    -Despite repeated warnings about partitioning windows in the ubuntu installer, I did this anyway, assigning 140 gigs to ubuntu and 500 to windows Now, my computer won't boot into anything but Ubuntu  -in Gparted, it still shows that I have two partitions, and windows 7 boot loader -However, I can't boot into the non-linux partition, and boot loader says I need a recovery disk.  My question is does anyone know if what I've done is fixable? I'm hoping that I can fix it using the way outlined in this thread:   Thanks for the help everyone!  Note: gparted shows:    Foudn linux image: /boot/vmlinuz - 3.13.0.30 - generic   Found linitrd image: /boot/initrd.img - 3.13.0 - 30 - generic   Found linux image: /boot/vmlinuz - 3.13.0 - 24 generic   Found  initrd image: /boot/initrd.img - 3.13.0 - 24- generic   memtest   memtest   Found windows 7 (loader) on /dev/sda1
Can't boot Windows 7 after installing Ubuntu I installed Ubuntu yesterday alongside Windows 7 and whenever I start my computer I don't have the option to boot Windows. When the computer starts it goes straight to Ubuntu without giving me an OS selection menu. When it goes to Ubuntu it gives me Ubuntu repair options and Ubuntu normal start option. I still have all of the Windows 7 files on my hard drive, but Windows 7 has no way to boot.
Google Chrome error: Error initializing NSS without a persistent database It was working properly before, suddenly it stopped working. When I tried to open by clicking on its icon, but nothing happens.  As already here are many questions related to this, but none of them are working for me. I already checked  and .  I uninstalled Chrome by following the instructions from .  sudo apt-get purge google-chrome-stable rm ~/.config/google-chrome/ -rf   Again I installed Chrome by:  sudo apt-get install google-chrome-stable   But the problem is still thesame.  When I enter google-chrome in terminal I get following error.  [12289:12323:0723/014456:ERROR:nss_util.cc(744)] Error initializing NSS with a persistent database (sql:/home/maddy/.pki/nssdb): libsoftokn3.so: cannot open shared object file: No such file or directory [12289:12323:0723/014456:ERROR:nss_util.cc(212)] Error initializing NSS without a persistent database: NSS error code: -5925 [12289:12323:0723/014456:FATAL:nss_util.cc(214)] nss_error=-5925, os_error=0 As expected, Nvidia drivers have reduced my customizations. I can't login to Unity 3D session. I can't find any content to help me to uninstall the driver and I don't know what to do as I have never uninstalled them before. What do you call a person who is never content with anything that is given to him? I am looking for an adjective for a person who, no matter what you give him/her (materially or otherwise), is never content and always expects more. Mount cifs Network Drive: write permissions and chown I have access to a cifs network drive. When I mount it under my OSX machine, I can read and write from and to it.   When I mount the drive in ubuntu, using:  sudo mount -t cifs -o username=${USER},password=${PASSWORD} //server-address/folder /mount/path/on/ubuntu   I am not able to write to the network drive, but I can read from it. I have checked the permissions and owner of the mount folder, they look like:  4.0K drwxr-xr-x  4 root root    0 Nov 12  2010 Mounted_folder   I cannot change the owner, because I get the error:  chown: changing ownership of `/Volumes/Mounted_folder': Not a directory   When I descend deeper into the network drive, and change the ownership there, I get the error that I have no permission to change the folder´s owner.  What should I do to activate my write permission? Is $A\triangle B := A\cup B-A\cap B $ a suitable definition for the symmetric difference of two sets $A$ and $B?$ Or is $A\triangle B := (A-B) \cup (B-A) $ only allowed? sliding a tangent line along a curve Difference between "I'm home" vs "I'm at home" Do these define metrics on $\mathbb{R}$? When the phrase is used as an object, why so many native speakers are saying "you and I" instead of "you and me"? I'm not a native speaker but I thought "you and me" is correct. Not sure if this falls into the same category, but "Just between you and me" sounds more natural than "Just between you and I". Given the following code (that doesn't work):  while True:     #snip: print out current state     while True:         ok = get_input("Is this ok? (y/n)")         if ok.lower() == "y": break 2 #this doesn't work :(         if ok.lower() == "n": break     #do more processing with menus and stuff   Is there a way to make this work? Or do I have do one check to break out of the input loop, then another, more limited, check in the outside loop to break out all together if the user is satisfied? When I create a clan in the multiplayer menu, it says clan created but I cannot add or invite people to my clan. I go to create a new one assuming the request was canceled or not entered correctly, it says clan name already exists as if someone else created it.   Is this a bug? Did I do it wrong? Or am I missing something?   I'm on the PS3. Will this also happen on my Xbox 360 Version? Why does N[1.000 01, 10] return 1.00001, but N[1.000 001, 10] returns only 1.? Proving divisibility of expression using induction I'm working on a jet in blender. While thinking about the final scene, I wondered if there was a way to create schock diamonds(also known as Mach diamonds, Mach disks, Mach rings, donut tails or thrust diamonds) in blender.  Hopefully somebody can help, I haven't found anything online.      picture from wikipedia  picture from Tom Clancy's H.A.W.X  thanks for any tips.  tags: mach, schock, diamond, jet, exhaust, afterburner, engine, Physical phenomena  edit: added some pictures, Correcting projection of 360° content onto a sphere - distortion at the poles I'm using the Autopano Giga 4.4 and Autopano Video Pro 2.6 to stitch and create spherical content, but I've recently moved into wanting to create 360° tours via Unity. I know this is partly a developers question, but if anyone out there can help me with the right specs for exporting a spherical image or video from Giga to use to create the image for the inside of the sphere on Unity, I'd appreciate it!  Experimenting with Premiere and FCPX to edit highlight reels of spherical content, I've had seamless experiences created. For some reason in Unity, the images appear to be stretched around the sphere wrong and it's creates issues on the top and bottom of the image:    The image shown is the bottom of the sphere. I'm using the Android platform to hopefully turn these tours into apps when completed. Thank you for any help! Chapter number starts at 2 not 1 How can I start my chapter from "Chapter 2" instead of "Chapter 1".  I am preparing LaTeX document for each chapter. when I put \chapter{Introduction}, it produces "Chapter 1" Introduction. However I want it to be "chapter 2" Introduction instead. Prove by mathematical induction that $n^3 - n$ is divisible by $3$ for all natural number $n$ 10% rule for sample sizes In an introductory stats book by Nicole Radziwell "Statistics the easy way with R" , an assumption used  for nearly every statistical test (e.g.t-tets, anova, etc) is that the sample size should not be more than 10% of the population size (where the population size in known).   I havent seen it mentioned in other introductory stats books. My question is: how important is theis assumotion and what is the reason for it?  The author didn't say where this comes from (at least as far as I could see). A bit of googling suggests that it refers to making a simple random sample without replacement, if the sample size is above 10% then the observations wont be (approximately) independent, and indepedence of observations is an assumption stated in most textbooks.   In the case where you have a small population (e.g. &lt;50), should you give up on this assumption because it results in sample sizes too small to get decent estimates of variability and to check other assumptions such as normality.    Thank you for any insights. Getting a window's PID by clicking on it Is there any package which shows PID of a window by clicking on it? She don't know that she's a lucky girl Here's from an old song (1963) "" by Lesley Gore.       She don't know that she's a lucky girl   Here's another example, "Silence is Golden" (1964) by The Tremeloes [YouTube ]      Oh, don't it hurt deep inside to see someone do something to her.   I wonder how common it is to say "She don't" or "don't it". Do native English speakers often use these?  By the way, Lesley Gore is American, and the Tremeloes is British.
