I was upgrading my ubuntu from 11.10 to 12.04 LTS but the power went off.  So when i restarted by laptop there was a black screen that came. Then I downloaded 12.04 from windows 7. It is rebooting from windows boot manager. Now how do i remove 11.10 ubuntu.
I dual booted ubuntu 11.04/11.10 a while ago with a USB stick and i want to uninstall it.   I would like to completely uninstall the old version and get 12.04.  I have a 64 bit laptop. Please help!
Cut strokes from other shapes via pathfinder Fixed page header overlaps in-page anchors How do I answer "Where do you work?" What are the main purposes to ask someone 'Where do you work?' apart from to find out the type of place he or she works in?  I can answer:     I work in a shop.   I work in a hospital.   I work in an office.   But what other things can (or should) I use as a reply to this question?    Extra question:  sometimes I see     I work at a shop.    I work at a hospital.    I work at an office.   What's the difference between 'at' and 'in' in this case? Often, when making a command block contraption, you need to set an entity's data tag. These tags can sometimes be very long, with many layers of nested curly and square brackets. For example, this is the command to summon a villager with a single custom trade:  /summon Villager ~ ~ ~ {Profession:3,Career:2,Offers:{Recipes:[{buy:{id:minecraft:diamond,Count:6b}},sell:{id:minecraft:diamond_hoe,tag:{ench:[{id:16s,lvl:10s}]}]}}   The single-line command block interface of Minecraft makes it incredibly difficult to find and fix errors, especially when it comes to mismatched brackets. In fact, for illustration purposes, I put an error in the above command.  What techniques can I use to find and fix unbalanced square or curly brackets when writing long and complicated data tags? Are other players able to see you on their map in Pokemon Go? I am concerned that if I use the game, stalkers and other such people would be able to find me. I have searched for an answer for this question on other forums, but have yet to find the answer. Summary table with a field that shows components of each summarized record Does a finally block always get executed in Java? cube collider losing shape upon rotation I'm not sure what's going on here. I have a cube which I have turned into a rectangle; it's a child of a plane which is the "ground" so that they share rotation (this is a pinball table).   To create these cubes, I just used the create => 3d shape => cube/plane option. No packages are used.   The issue is when I rotate the rectangle, the collider visibly becomes wrong.  This is before rotation:    This is after rotating on the y axis:    The collider does seem to rotate, but not at the correct amount. Can anyone shed some light as to what's going on here?  Here's the inspector and hierarchy:      I also tried making the plane a cube, it didn't change anything. If we allow that the energy to allow quantum tunnelling through a potential barrier has been borrowed by the Heisenberg energy-time uncertainty relation, from the vacuum energy. How is the borrowed energy paid back? How do I make a bootable USB OS X installer on a Mac? Does anyone have a Terminal command-line recipe for making a new bootable USB flash drive for one of the new MacBook Air's?  Is there a way to dd copy the USB boot device that comes in the box and make the new copy bootable?  I'd like to make a new backup copy of the USB rescue device for my MBA, preferably on a much larger flash drive with room for a backup of some of my working directories.  Added:  And is it possible to make, not just a rescue drive, but a bootable USB drive that will boot a fully updated version of the OS (say 10.6.8 or later)?  If so how on a MacBook Air 11, and how big a USB stick will this require? I recall being somewhat impressed by a novel I read a few years back – this book may be less than five years old – which featured a college-aged man.  He had a laptop which transformed into a troll goblin that served as his familiar.  In the story's universe, mages had switched to the Internet for most of their magic &amp; communication.  The main character was essentially a magical hacker, and spent much of the book fighting against his evil aunt (I think, I know it was a female relative) with the help of his cousin.  Older forms of magic were also featured, including using special paintings as magical portals, and spells being whistled by wizards.  It features a scene at a gas station where the laptop is disabled by a virus, and the main character whistles a spell to reanimate dinosaurs from the gasoline.  Is this ringing any bells? Fubini's theorem for series with dependent indices As a part of a proposition about power series that I am trying to prove I have to show that  $$ \sum_{m=0}^{\infty} \left(\sum_{n=m}^{\infty} \frac{n!}{m!(n-m)!}(b-a)^{n-m}c_n\right)(x-b)^m = \sum_{n=0}^{\infty}c_n(x-a)^n$$  Proof: What I have done so far is to show that  $$\sum_{m=0}^{n} \frac{n!}{m!(n-m)!}(b-a)^{n-m}(x-b)^m = (x-a)^n $$  So the next idea is to use Fubini's rearrangement theorem for infinite series (I have also shown that the series are absolutely convergent). However, the theorem does not accomodate for dependent indices. Intuitively (using triangular summation), I think that the proper way to interchange series would be \begin{equation*} %\begin{array}{ll} \sum_{m=0}^{\infty} \sum_{n=m}^{\infty} \frac{n!}{m!(n-m)!}(b-a)^{n-m}c_n(x-b)^m = \sum_{n=0}^{\infty} \sum_{m=0}^{n}\frac{n!}{m!(n-m)!}(b-a)^{n-m}c_n(x-b)^m %\end{array} \end{equation*} and thus  $$=\sum_{n=0}^{\infty} c_n(x-a)^n$$ However, I do not know how to perform this step rigorously in case of infinite summation.

Virus added .mbed File Extension The files on my PC's 2 drives have been altered by a virus; all files on both drives now have an extra extension of ".mbed"  Here you have a screenshot to get my point:   So what is the shortcut way for me to correct all these file extensions? Prove that $(\mathbb{Z}_n , +)$, the integers $\pmod{n}$ under addition, is a group. Prove that $(\mathbb{Z}_n , +)$, the integers  $\pmod{n}$ under addition, is a group.  To show that this is a group, I know I need to show three things (in our text, we do not need to show that addition is closed-- rather, we show these three items):  $(a)$ Associative Law  $(b)$ Existence of Identity  $(c)$ Existence of Inverse  This is what I have been working with so far:     $(a)$ Associative Law:   First, assume that $n$ is a composite number and that $a,b \in \mathbb{Z}$ s.t. $a=nx$ and $b=ny$ for some integers, $x$ and $y$. Then $a+nx+nx=n(x+y)$.     So, this is where I am stuck for the Associative Law. I'm not sure if I am headed down the correct path to show that $\mathbb{Z}_n$ is associative.      $(b)$ Existence of Identity:   Generally, when showing the existence of an identity we can use this information for addition :  $a + 0 = 0 + a =a$.    I am unsure how to insert the modular portion of the definition into the existence of this identity. I realize that for addition, we generally look at $0$ (rather than $1$ for multiplication).     $(c)$ Existence of Inverse: I need to show that for each element $a \in \mathbb{Z}_n$ that $a^{-1}=-a$. Again, I do not know how to insert the modular portion of definition into this aspect of the proof.   My question is how to incorporate this modular information into the proof that this is a group. We have not covered the integers modulo $n$, binary operations, nor groups in my intro to proofs course. I am trying to read my text to figure out how to prove this, but have a difficult time reading and interpreting math speak. Story about a sentient star system, in a 50s or early 60s anthology Story about a sentient star system, possibly in f&amp;sf anthology from 50s or early 60s.

Why is wine made 'from' grapes, but tables are made 'of' wood? (1) Wine is an alcoholic beverage made from fermented grapes or other fruits. (Wikipedia) (2) Tables were made of marble or wood and metal (typically bronze or silver alloys), sometimes with richly ornate legs. (Wikipedia)  Why is 'from' used in (1), whereas 'of' is used  in (2)? Is it a stylistic choice whether to use 'of' or 'from'? Or, in case of chemical changing, differently from changing in shape only, 'from' is preferable? I would like to redirect a URL with uppercase characters http://localhost/A/B to a lowercase version http://localhost/a/b using the .htaccess file. Using regex I can capture A and B but is it possible to convert them to lowercase?
