In opened msconfig.exe window, General tab, I set the startup selection to Diagnostic startup. After rebooting system windows didn't boot, even in safe boot. Operation system is Windows 7. How can i resolve it?
I have a HP-G62 B17S laptop, which has Windows 7 Home Edition 64-bit.  I read on a blog about a setting in msconfig.exe (Windows System Configuration utility):     Boot > Advanced options > Number of Processors   This was showing 1 for me but I have a dual core AMD Turion, so I changed the setting to 2. Next to it was a Maximum Memory setting (which was unchecked). I checked it and made sure it was max 4096; my system has 4GB RAM.  After restarting the laptop, it now gives an error:     Windows Error Recovery   Windows failed to start   I can choose from two options:   Launch Startup Repair Start Windows normally.   When I select Startup repair, it goes on to give another error:     Windows Boot Manager       Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:         Insert your Windows installation disc and restart your computer.    Choose your language settings, and then click "Next."     Click "repair your computer."      I do not have the Windows installation disc for this OS version - the manufacturer did not send it to me when I purchased the laptop.  If I try to start Windows normally it takes some time and then gives the same error message.  I tried inserting another installation disc of Windows 7 Professional Edition 64-bit (available from my other laptop), and restarting, but no repair menu comes up.  I also tried restarting the laptop, pressing F8 to enter Advanced Startup Options and selecting to boot with the Last known good configuration, or starting in safe mode - neither option gives any success. This time it gives a Blue Screen of Death with the following message:     A problem has been detected, and Windows has been shut down to prevent damage to your computer - BAD_SYSTEM_CONFIG_INFO   It then does a crash dump of the memory and restarts with the same options of repairing or starting Windows normally as earlier.   What exactly seems to be the problem here and its cause? What are my options now to restore/repair my Windows 7 OS to a working condition? Would the manufacturer send a recovery/repair disk for this if I called them? The laptop should be in warranty period - it was purchased six months ago. I have a Ubuntu 10.04 bootable CD. Is there any way to boot into Ubuntu, and repair Windows from there? Are there any other way to recover the OS? (I have an access to a working Windows Vista HP Laptop, if that helps)   EDIT Ok, it was able to boot through the Win-7 professional Installation disc, but even after doing Startup repair, and System restore, It still does not boot into the original Win-7.
Prove that any conjugate of $a$ has the same order as $a$. I am trying to prove that any conjugate of $a$ has the same order as $a$.  Let $G$ be a group and let $a \in G$.  An element $b \in G$ is called a conjugate of $a$ if $b=xax^{-1}$.  My professor gave us a hint.  Prove $a^k=e$ iff $b^k=e$ for all $k \in \mathbb{Z}$ implies $o(a) = o(b)$.  My first move is to $b^k = (xax^{-1})^k = (x^{-1})^ka^kx^k = (x^{-1})^kex^k = (x^{-1})^kx^k=x^{-k+k}=x^0$  I am not sure that I am doing this correctly?  I am trying to get $b^k=e$.  However when I raise $(xax^{-1})^k$, I am not sure if I what I have done is correct?  I am kind of confused here. How to find event listeners on a DOM node when debugging or from the JavaScript code? I am programming with normal pointers, but I have heard about libraries like Boost that implement smart pointers. I have also seen that in Ogre3D rendering engine there is a deep use of shared pointers.  What exactly is the difference between the three, and should I stick on using just a type of them? Algebraic extension of perfect field in which every polynomial has a root is algebraically closed Let $F$ be a perfect field, i.e. every irreducible polynomial over $F$ has distinct roots in the algebraic closure of $F$. Suppose that $K$ is an algebraic extension of $F$ with the property that every non-constant $p(X) \in F[X]$ has a root in $K$.   I want to show that $K$ is algebraically closed, i.e. that $K = \overline{F}$, the algebraic closure of $F$.  If $K$ were a normal extension of $F$, this would follow immediately: Let $\alpha \in \overline{F}$ and $m(X)\in F[X]$ its minimal polynomial. By our assumption, $m(X)$ has at least one zero in $K$. Since $K$ is a normal extension of $F$, it thus contains all other roots of $m(X)$ including $\alpha$.  I don't have an idea as to how to show that $K$ is a normal extension. How to renew an expired keypair with gpg What is the best way to renew a gpg key pair when it got expired and what is the reason for the method?  The key pair is already signed by many users and available on public servers.   Should the new key be a subkey of the expired private key?  Should it be signed by the old (I could try to edit the key and change the date of expiration to tomorrow)? Should the new key sign the old? How to find out where an error occurs? Is there a way to detect if a browser window is not currently active? Do immature fruits perform photosynthesis? Most immature fruits are green: peppers, pine cones, plums, lots of them. I want to know if the green is from chlorophyll in the cells. Do the fruit cells perform photosynthesis? When you cover a green stem or leaf, it will turn pale and stretch. That is because the stems have little need for chlorophyll in the dark, which is why they are pale. They stretch because the auxins in the stems are not destroyed by the photons, and the stems stretch out and topple over. If a green fruit is covered, will it turn pale and stretch like that? As a programmer, I have no problem with seeing or using "and/or" in technical documentation. For example,     I can upvote an answer that satisfies me and/or mark it as accepted.   That's perfectly good English to me. However, if I were writing a novel, or even just an essay, or — heaven forbid — a poem, "and/or" would seem extremely out of place.  My question is, what should I be using instead? (I solemnly swear I will not use that knowledge to actually write a poem.) A man wonders why perforations don't work. He decides nothing is the strongest thing in the universe. He exploits his finding. I'm running an SSH server on my personal computer. The log had many people(or bots?) repeatedly trying to log in to my server (that is before I changed the default port), which made me a little freaked out. I was worried about their dictionary attacks or brute force password guessing.  But then if you type wrong password (or wrong username), the server waits for about 2 seconds before it asks for password again. So an attacker can try one password per 2 seconds. So I concluded that these attacks aren't that great a threat (as long as your password does not consist of dictionary words.) Am I correct?

So, I thought at the very least that I'd raise some awareness. Can I boot a Live USB fully to RAM, allowing me to remove the disk? I have a live USB made with the standard Ubuntu disk image creator for 16.04 LTS. In the current state, I can boot to this disk, but it still requires the original USB to run properly at all times.  Attempting to pull the drive and use the system generates a large amount of I/O errors, further suggesting that the USB drive is actually needed for things not already loaded into RAM (For example, Firefox worked without the USB, but I used it once before already. apt, on the other hand, did not.)  Is there a way to copy the entire Ubuntu live disk to RAM, so I can remove the drive and free up a USB slot for other things? Make terminal use pageup/pagedown instead of shift-pageup/shift-pagedown? I've grown quite weary of shift-pgup to page up in gnome terminal, the command line, terminator, and guake, etc.  Any way to easily make these apps use the straight page-up and page-down keys for paging around? G-test vs Pearson's chi-squared test Why is vote time missing in the SE data dump and SEDE? Is there a particular reason why vote times are omitted in the data dump?  IMO this could be a very useful data-set. Is this one of the steps that was done to anonymize the data, or does it simply not exist? This would be a very good addition to future dumps to help build time-based relationships, which are currently very rigid and full of assumptions. Why is "women" pronounced the way it is? As far as I know, it is the only word where wo is pronounced as wee. What is the reason for this? Does it have to do with the origin of the word? Are expletives (cursing, swear words or vulgar language) allowed on SE sites? Summing Up A 2D Array The UK Visas and Immigration Directorate publishes  that provides helpful tips that can result in successful visa applications.
